Background: An ischemic stroke takes place when a blood vessel supplying the brain is blocked and blood circulation to a part of the brain is damaged. A lacunar stroke occurs due to one of the arteries that provide blood to the brain's deep structures is blocked. Case Study: A 55-year-old male patient have right cerebrovascular accident (CVA) with left hemiparesis on 16th of August 2019. Normal result was seen by brain Computed Tomography (CT) scanning. Magnetic Resonance Imaging (MRI) brain was done resulted in hyperintense lesion in right pons and foci and Magnetic Resonance Angiography (MRA) was done and resulted in severe basilar artery stenosis.

This is a case study of a 47-year-old Caucasian male whose chief concern was left lower leg swelling for 1 month. A unilateral lower extremity venous duplex examination was performed. The results concluded that the distal femoral vein was occluded to the distal popliteal vein. Incidentally, a hypoechoic region in the distal thigh near the distal femoral artery was noted by the technologist. The patient was placed on anticoagulation and was told to return for further examination if there was no relief. Three months later, the patient continued to experience lower left leg swelling and returned for another sonogram. The hypoechoic region was seen again in the distal thigh and remained occluded. A computed tomographic arterial (CT-A) and magnetic resonance imaging (MRI) were ordered for further investigation of the hypoechoic area. The CT-A and the MRI revealed the presence of a mass in the distal thigh. The mass was biopsied and diagnosed as a leiomyosarcoma, grade 1. The mass caused the compression and occlusion of the distal femoral vein. The mass was removed, along with a portion of the distal femoral artery due to involvement of the artery within the mass. The artery was repaired with a graft.

✓ The authors present two cases of herpes simplex encephalitis (HSE) in which computerized tomography (CT) scanning and magnetic resonance imaging (MRI) were performed. They also review the literature on the use of these imaging modalities in cases of HSE. The striking changes noted in these cases on T2-weighted magnetic resonance images in comparison to the CT findings suggest that MRI will help speed recognition of nonhemorrhagic HSE abnormalities.

New Onset

Gadolinium (Gd) is a based contrast agent is used for Magnetic Resonance Imaging (MRI). In India, gadobutrolhas been is approved for MRI of the Central Nervous System (CNS), liver, kidneys, and breast. It has been noted in several studies that the accumulation of gadolinium occurs in different structures in the brain. Patients with Multiple Sclerosis (MS) are regularly followed up with MRI scans and MRI with contrast enhancement is the most common method of distinguishing new-onset pathological changes. Developments in technology and methods in artificial intelligence have shown that there is reason to map out the X-ray technician’s work with examinations and medicines administered to patients may be altered to prevent the accumulation of gadolinium.

A 5-year-old Indian boy presented with subacute onset regression of milestones associated with seizures and spasticity. The symptoms started after an attack of measles. The magnetic resonance imaging (MRI) of the brain showed cavitating leukodystrophy with posterior predominance. Molecular analysis of the APOPT1 gene, a recently described gene associated with mitochondrial leukodystrophy, showed the patient to be homozygous for a 12.82-kilobase deletion, including coding exon 3. Deletion of exon 3 produces a frameshift, predicting the translation of a truncated protein (p.Glu121Valfs*4). The patient was started on mitochondrial cocktail regimen of thiamine, riboflavin, coenzyme Q and carnitine. Although he initially showed some improvement, he died 6 months after the onset of his illness.

Backround/Aim. Sedation is necessary in children undergoing magnetic resonance imaging (MRI) to ensure motionless. The success of sedation is typically measured by two factors: safety (lack of adverse events) and effectiveness of the procedure (successful completion of the diagnostic examination). Propofol is frequently used to induce deep sedation in children. However, increased doses of propofol may lead to oversedation and respiratory depression. The aim of the study was to investigate sedation in children using propofol with midazolam in regard to efficacy, adverse events and time to return to presedation functional status. Methods. We investigated 24 children prospectively. Sedation was introduced with a single bolus of intravenous (iv) midazolam 0.1 mg/kg followed by repeated small iv boluses of propofol until sufficient depth of sedation was obtained. The outcome of sedation was measured by the induction time, sedation time, need for additional sedation, respiratory events, cardiovascular events and sedation failure. Results. Median age of children was 4.72 ? 3.06 (1.1-12.3) years and their body weight was 21.3 ? 11.9 (11-60) kg. Average propofol bolus dose for induction was 1.76 ? 0.9 (0.5-4) mg/kg. The induction time was 8.88 ? 2.92 (5-15) min, and sedation time 28.39 ? 8.42 (20-50) min. Additional sedation was necessary in 3 (12.5%) patients. Unsucesfull sedation or significant adverse events were not observed. Conclusion. The presented sedation technique for children undergoing ambulatory MRI of the brain is safe and adequate. This sedation regiment provides short induction time, fast recovery, stable cardiorespiratory conditions and rarely demans additional sedation.
