Preoperative cerebral angiography nearly doubles the rate of diffusion-weighted imaging lesion detection following minimally invasive surgery for intracerebral hemorrhage.

Background: Diffusion-weighted imaging (DWI) lesions have been linked to poor outcomes after intracerebral hemorrhage (ICH). We aimed to assess the impact of cerebral digital subtraction angiography (DSA) on the presence of DWI lesions in patients who underwent minimally invasive surgery (MIS) for ICH.

Methods: Retrospective chart review was performed on ICH patients treated with MIS in a single health system from 2015 to 2021.

Diffusion Weighted Imaging in Spine Tumors.

Diffusion weighted imaging (DWI) has developed into a powerful tool for the evaluation of spine tumors, particularly for the assessment of vertebral marrow lesions and intramedullary tumors. Advances in magnetic resonance techniques have improved the quality of spine DWI and diffusion tensor imaging (DTI) in recent years, with increased reproducibility and utilization. DTI, with quantitative parameters such as fractional anisotropy and qualitative visual assessment of nerve fiber tracts, can play a valuable role in the evaluation and surgical planning of spinal cord tumors.

A morbid coexistence: thrombosed descending thoracic aorta aneurysm and aortic insufficiency with aortic diastolic reverse flow.

A 76-year-old woman presented with difficulty in speech and weakness on right arm and leg. Her medical history was remarkable only for uncontrolled hypertension for a long period. Dysarthria, right central facial paralysis, right hemiparesis and hypoactive deep tendon reflexes were noticed on neurological examination.

Quantitative evaluation of ischemic myocardial scar tissue by unenhanced T1 mapping using 3.0 Tesla MR scanner.

Purpose: We aimed to use a noninvasive method for quantifying T1 values of chronic myocardial infarction scar by cardiac magnetic resonance imaging (MRI), and determine its diagnostic performance.

Materials And Methods: We performed cardiac MRI on 29 consecutive patients with known coronary artery disease (CAD) on 3.0 Tesla MRI scanner.

Evaluation of resistive index using color Doppler imaging of orbital arteries in geriatric patients with hypertension.

Background And Aim: Resistive index (RI) is an indirect measurement of blood flow resistance that can be used to evaluate vascular damage in ophthalmologic disease. The purpose of this study was to evaluate the association between RI values of orbital arteries using the color Doppler imaging (CDI) in geriatric hypertensive patients with or without retinopathy.

Setting And Design: Designed as a cross-sectional study.

Joubert syndrome: the clinical and radiological findings.

Joubert syndrome is a rare disease characterised by clinical and radiological findings. Among the classic clinical findings of JS are hypotonia, ataxia, mental-motor retardation, respiratory and opthalmological findings. The paediatric cases included in the study comprised nine patients.

Forty-five degree wrist angulation is optimal for ultrasound guided long axis radial artery cannulation in patients over 60 years old: a randomized study.

Arterial cannulation is a common anaesthetic procedure that might be challenging and time-consuming in elderly patients. To establish an appropriate wrist joint position for arterial cannulation is crucial for ultrasound (US)-guided cannulation success. This study aimed to find out the optimal wrist joint angle for long axis in-plane (LA-IP) US-guided approach in radial artery cannulation in elderly patients.

Assessment of lower extremity arterial blood flow in females with knee osteoarthritis.

To investigate whether blood flow in the lower extremity arteries changes in patients with osteoarthritis (OA) using color Doppler ultrasonography. The study comprised 39 female patients with osteoarthritis and 30 healthy female controls. The patients were evaluated using visual analogue scale (VAS) at rest and the Western Ontario and McMaster Universities Arthritis Index (WOMAC).

The use of sonoelastographic elasticity index to differentiate benign and malignant thyroid nodules.

Purpose: The aim of this study is to evaluate the elasticity index of thyroid nodules by sonoelastographic imaging, and to determine the cut-off value to distinguish malignant nodules from benign nodules with optimum sensitivity and specificity.

Materials And Methods: Fine needle aspiration biopsy (FNAB) of 84 cases were evaluated with B-mode US and Sonoelastography (USE) preoperatively. The elasticity score (ELX 2/1) index of the nodules were calculated.
