Introduction: Stroke is the second leading underlying cause of death globally and the leading cause of disability in adults. Stroke diagnosis should be performed quickly and efficiently to eliminate other potential causes of neurological deficits and to assess the time since the onset of clinical symptoms. Computed tomography (CT) and magnetic resonance imaging (MRI) are essential methods of detecting and evaluating stroke type and treatmentoptions. Diffusion and perfusion MR imaging is recommended for early stroke diagnosis, as well as for the selection of patients for recanalization therapy, and is considered effective in assessing treatment outcomes. The objectives of this study were to demonstrate the diagnostic value of diffusion and perfusion imaging in the diagnosis of acute ischemic stroke, analyze the role of magnetic resonance imaging in the selection of patients with acute stroke for recanalization therapy, and assess the effect of acute stroke complicity.Material and methods: The research is designed as a systematic review of the primary scientific research literature, which was published in English in relevant scientific databases (PubMed, Google Scholar, Medline) from 2014 to 2021.Results: 14 scientific research papers were singled out and the general characteristics of the study were analyzed (country, authors, year of publication, title of the study, type of study, study objectives, research methods, results and conclusion). A quality assessment of the included studies with cohort design and randomized controlled studies was performed, and most belong to the category of high-quality studies with a smaller number of medium-quality studies. The overall percentage of detected AIS cases in isolated studies using the DWI and/or PWI sequence was 90.8%. At the same time, the outcome of recanalization therapy was assessed using MRI studies (the number of patients who developed adverse events with functional data outcome 30 or 90 days after the procedure was observed). Comparison of MRI and CT imaging protocols provided data on the total percentage of detected acute stroke cases using CT imaging protocols (68.9%) and MRI imaging protocols (88.5%), which is why MRI is considered a superior method.Conclusion: Although CT is a suitable method for visualizing bleeding and also for early differentiation of hemorrhagic from ischemic stroke, if MRI imaging is available, it is recommended to use DWI, PWI, MRA sequences for a more accurate diagnosis of stroke in the acute phase.
OBJECTIVE To present a rare disease, and to point out that clinical manifestations treated for a long period of time without an adequate response to therapy may be a manifestation of a rare disease. CASE REPORT We present the case of a 3-year-old girl who had been drinking a large amount of water for the previous ten days with frequent urination, and who experienced the worsening of symptoms of scalp dermatitis that had been treated for a year without success. Physical examination revealed a maculopapular rash on the scalp, neck and both ear shells, and exophthalmos of the right eye with periorbital edema. Magnetic resonance imaging of the orbits showed extensive lesions of the skull bones. Further diagnostic evaluation revealed similar lesions in other bone structures. Biopsy of the affected region, microscopic and immunohistochemical analysis led to diagnosis of Langerhans cell histiocytosis. CONCLUSION Langerhans cell histiocytosis mostly occurs in the first three years of life. The incidence is 4-5 patients per million children under 15 years of life. The clinical presentation is highly variable, and can range from isolated, self-healing skin and bone lesions to life-threatening multisystem diseases. Due to the diverse clinical picture, that is often unrecognized, these patients are often referred to other specialists, resulting in the treatment of individual symptoms rather than the underlying disease.
Stroke remains one of the leading causes of death and disability in Europe. The European Stroke Action Plan (ESAP) defines four main targets for the years 2018 to 2030. The COVID-19 pandemic forced the use of innovative technologies and created pressure to improve internet networks. Moreover, 5G internet network will be helpful for the transfer and collecting of extremely big databases. Nowadays, the speed of internet connection is a limiting factor for robotic systems, which can be controlled and commanded potentially from various places in the world. Innovative technologies can be implemented for acute stroke patient management soon. Artificial intelligence (AI) and robotics are used increasingly often without the exception of medicine. Their implementation can be achieved in every level of stroke care. In this article, all steps of stroke health care processes are discussed in terms of how to improve them (including prehospital diagnosis, consultation, transfer of the patient, diagnosis, techniques of the treatment as well as rehabilitation and usage of AI). New ethical problems have also been discovered. Everything must be aligned to the concept of “time is brain”.
A fetus with suspicion for holoprosencephaly and various brain malformations were seen on ultrasound and send for magnetic resonance imaging (MRI). Immediately after the birth of the female patient ultrasound and MRI was made which confirmed lobar holoprosencephaly. Fetal MRI stands out as a powerful diagnostic tool for detecting anomalies and other disorders. By developing new sequences and raising image quality will enable visualization of small details.
Purpose Infantile hemangiomas (IH) are the most common benign vascular tumors of infancy. Ocular complications due to orbital IH include strabismal, deprivational, or anisometropic astigmatism, and visual loss secondary to amblyopia. Observations We report a case of a two-month-old female infant with a severe deep orbital IH. The diagnosis was established by clinical examination and magnetic resonance imaging (MRI). The patient was treated with oral propranolol for six months. Complete tumor regression was observed clinically and by MRI following the treatment. The patient showed no adverse effects or tumor recurrence at the 14-month follow-up. Conclusions and Importance Despite its benign nature, periorbital IH requires a rapid diagnosis and prompt treatment to prevent vision loss, particularly in infants. Our case confirms that oral propranolol may be regarded as a safe drug for periorbital IH with an excellent outcome.
Uvod: Spinalni tumor predstavlja patološku tkivnu masu smještenu unutar kičmene moždine, kičmenog kanala ili vertebralne kolumne. Incidenca primarnih spinalnih tumora je mala i prema navodima iz literature iznosi oko 0,58 do 0,71 na 100.000 pacijenta u godini. Preko dvije trećine svih primarnih spinalnih tumora otpada na tumore intraduralne ekstramedularne lokacije, a ostatak na intraduralne intramedularne tumore. Uvođenjem MRI u kliničku praksu došlo je do revolucije u karakterizaciji spinalnih tumora kroz detaljnu i direktnu vizualizaciju koštane srži i kičmene moždine u više ravni, čime je omogućeno ranije otkrivanje i liječenje kako ekstraduralnih tako i intraduralnih tumora. Iako imidžing putem CT-a daje pouzdane informacije u pogledu procjene matriksa tumora i koštanih promjena kod ekstraduralne lokacije, MRI je metod izbora u procjeni mekotkivne ekstenzije tumora, infiltracije koštane srži i eventualne intraspinalne propagacije. Ciljevi: 1. Prikazati ulogu imidžinga magnetnom rezonancom kod evaluacije intraduralnih spinalnih tumora evaluiranih na Klinici za radiologiju Kliničkog centra Univerziteza u Sarajevu putem predavanja u vidu slikovnog eseja. 2. Klasificirati primarne i sekundarne spinalne tumore u odnosu na njihovo porijeklo iz ekstraduralnog, intraduralnog ekstramedularnog i intraduralnog intramedularnog kompartmenta uz razmatranje dijagnotičkog pristupa u kliničkoj obradi pacijenata s intraduralnim spinalnim tumorima. 3. Pružiti pregled MRI karakteristika različitih primarnih spinalnih tumora intraduralne lokalizacije.
Experience in managing thromboembolic complications of distal blood vessels during coil embolization in the case of subarachnoid hemorrhage (SAH) is still limited. This is the presentation of the case of a 23-year-old man with a ruptured small aneurysm who experienced thromboembolic occlusion during coil embolization. Mechanical thrombectomy resulted in complete recanalization of the occluded branches without ischemic complications. This case should be used for the use of mechanical thrombectomies as an effective rescue strategy and treatment of distal arteries occlusions of the brain.
Vertebral artery fenestration is a rare vascular anomaly. It most commonly occurs in extracranial segments of the vertebral artery. This congenital anomaly can occur during the various stages of embryonic development of the vertebral artery. This usually does not have clinical significance, but the possibility of associated anomalies such as saccular aneurysms and arteriovenous malformations should be noted. Awareness of vascular anomalies is key to avoiding iatrogenic injury during endovascular diagnostic and therapeutic interventions. Here, we present incidental findings of vertebral artery fenestration in a 46-year-old woman evidenced by CT angiography of the neck's blood vessells after I .V. contrast medium applications.
The clinical appliance of perfusion is being continuously developed and it is closely related to technology development. The role of perfusion neuroimaging in the management of acute stroke has been to prove reduced regional blood flow and to give the contribution in the identification of ischemic areas, respectively the regions of hypoperfusion that can be treated by thrombolytic and/or endovascular recanalization therapy. There are two main approaches to the measurement of cerebral perfusion by magnetic resonance. The aim of this article is to compare different measuring approaches of MR perfusion neuroimaging.
Aim To assess hand function and explore the relationship between hand function and neuroimaging findings in children with unilateral spastic cerebral palsy (US CP). Methods Hand function was assessed using Manual Ability Classification System (MACS, I-V). Brain lesions were divided into five groups: brain maldevelopment (MAL), periventricular white matter lesions (PV WM), cortical/subcortical gray matter lesions (C/SC GM), nonspecific and normal findings. Results Of 114 children with US CP (77 boys and 37 girls), 56 were with right-sided and 58 with left-sided involvement. MACS I was found in 49 (42.9%), MACS II in 19 (16.7%), MACS III in 19 (16.7 %), MACS IV in 9 (7.9%) and MACS V in 18 (15.8%) children (p=0.002). Computed tomography (CT) as the only neuroimaging has been done in 18 (15.8%), magnetic resonance imaging (MRI) at 94 (82.5%) children, whereas 2 (1.7%) children had neither CT nor MRI. The CT showed PV WM in eight (44.4%), C/SC GM lesions in 6 (33.3%), and normal findings in 4 (22.2%) children (p=0.709). The MRI showed MAL in 8 ( 8.5%), PV WM in 46 (48.9%), C/SC GM in 28 (29.8%), miscellaneous in 2 (2.1%), and normal finding in 10 (10.7%) children (p=0.0001). Mild hand dysfunction (MACS I and II) was assessed in 68 (59.7%) children, of which 33 had PV WM lesions (p=0.001). Conclusion Mild hand dysfunction in children with US CP has been significantly associated with PV WM lesions. The type of brain lesion may help to identify its timing and predict the level of hand dysfunction.
Multiple sclerosis is a chronic demyelinating disease of the central nervous system, that causes permanent disabilities. Diagnostics of this disease by magnetic resonance requires the appliance of corresponding protocols with the sequences that emphasize demyelinating plaques. Standard sequences T1 and T2 sometimes cannot clearly show demyelinating plaques, and it is necessary to work on perfecting the sequences that emphasize the changes in the brain formed as demyelinating plaques. The aim of the survey: The aim of the survey was to estimate the value of MR sequence with double inversion recovery (DIR) in discovering demyelinating lesions of the brain in multiple sclerosis (MS). Patients and methods of the survey: 22 patients were included in the survey, they were of both genders and different age. The patients were with diagnosed with multiple sclerosis. The patients underwent the scanning on MR apparatus 1.5 T. Comparison of DIR sequence to FLAIR and T2 W sequences were done. Result: DIR sequence proved significantly more MS lesions compared to T2W or FLAIR sequence, including intracortical, juxtacortical and paraventricular zone of the brain. In the infratentorial zone of brain, T2W sequence proved significantly more plaques compared to DIR and FLAIR. Conclusion: DIR sequence compared to T2W and FLAIR sequences discovered more demyelinating lesions in targeted regions that were examined. DIR sequence is a tool that contributes to easier and faster diagnostics of multiple sclerosis, needs to be included into the routine MR protocol of patients with MS, in order to discover more easily intracortical and juxtacortical MS lesions of the brain.
