Brain and Spinal Cord MRI Findings in Thai Multiple Sclerosis Patients.

Background: Previous studies have demonstrated different MRI characteristics in Asian and Western patients with multiple sclerosis (MS). However, the number of studies performed on Thai patients is still limited. Furthermore, these studies were conducted before the revision of the McDonald criteria in 2017.

Evaluation of Perienhancing Area in Differentiation between Glioblastoma and Solitary Brain Metastasis.

Purpose: Accurate differential diagnosis between glioblastoma and brain metastasis is important. We aimed to differentiate these tumors by evaluation of the perienhancing area.

Materials And Methods: Thirty patients with glioblastoma and solitary brain metastasis were included.

Grading Gliomas Capability: Comparison between Visual Assessment and Apparent Diffusion Coefficient (ADC) Value Measurement on Diffusion-Weighted Imaging (DWI).

Background: To compare diagnostic accuracy between DWI visual scale assessment and ADC value measurement of solid portion of the tumor in grading gliomas.

Methods: This retrospective study included 38 patients who had pathologically proven gliomas between January 2013 and August 2018 with 18 low grade and 20 high grade tumors. All patients underwent MRI and biopsy.

Preoperative MRI evaluation of meningioma consistency: A focus on detailed architectures.

Objectives: Meningioma is one of the most common primary intracranial tumors. Diagnosis by imaging is not difficult. However evaluation of tumor consistency is an important factor affecting the surgical outcomes.

DIFFERENCES OF MRI FEATURES BETWEEN TUBERCULOUS AND BACTERIAL SPONDYLITIS IN A TB-ENDEMIC AREA.

Pyogenic and tuberculous spondylitis are common causes of infectious spondylitis. The purpose of this study was to determine the specific MRI findings that can differentiate these two types of infectious spondylitis. This study retrospectively analyzed MRIs in patients diagnosed with infectious spondylitis from January 1, 2005 to December 31, 2009.

MR findings in spinal tuberculosis in an endemic country.

Introduction: Spinal tuberculosis (TB) accounts for 50% or more of skeletal tuberculosis. MRI is a helpful tool for spinal TB. MR findings in spinal TB however, may have several different patterns.

Cerebral angiographic findings in patients with non-traumatic subarachnoid hemorrhage.

Background: Even though ruptured intracranial aneurysm is a major cause of non-traumatic subarachnoid hemorrhage (SAH), non-aneurysmal SAH has a good prognosis with few neurologic complications. The gold standard for detecting the vascular pathology is digital subtraction cerebral angiography (DSA).

Objective: The primary objective of the present study was to clarify cerebral angiographic findings in patients with non-traumatic subarachnoid hemorrhage (SAH); to define the incidence of nonaneurysmal SAH.

Communicating hydrocephalus as a complication of eosinophilic meningoencephalitis.

The authors reported an adult patient with communicating hydrocephalus in eosinophilic meningoencephalitis. He presented with localized peritonitis and then developed eosinophilic meningoencephalitis. Angiostrongylus cantonensis was the causative agent.

Predictive CT features in ruptured abdominal aortic aneurysm.

Objective: To evaluate the CT findings including size of aneurysm, hyperattenuation crescent sign and focal discontinuity of mural calcification to predict the risk of ruptured aneurysm.

Material And Method: Records of 27 patients, who underwent Multislices Computed Tomography (MDCT) and required operative repair of abdominal aortic aneurysm from July 2000 to July 2003 were retrospectively reviewed Two radiologists evaluated the images by consensus, analyzing the aneurysm size, hyperattenuation crescent sign, and focal discontinuity of mural calcification.

Results: The authors found that the mean maximum AP diameters of the aneurysm in the ruptured and nonruptured group were 6.

Stroke in Asia.

The epidemic of cardiovascular disease across most of Asia is at a different stage from that in the West; the incidence and prevalence of stroke are increasing steadily, associated with nutritional changes and aging of the population. Epidemiologic data, crucial in combating stroke, have been relatively sparse in Asian populations, but a few international collaborative studies on stroke have been in progress for several years. Through these, we now know that ischemic stroke is actually the most frequent type of cerebrovascular accident in Asia, although hemorrhagic stroke remains more common in Asia than in the West.

Comparison of high-resolution computed tomography with pulmonary function testing in symptomatic smokers.

Purpose: To compare high-resolution computed tomography (HRCT) of lungs with pulmonary function in smokers diagnosed with emphysema.

Material And Method: The authors retrospectively reviewed 17 patients with a history of smoking and dyspnea, who underwent HRCT of the lungs and pulmonary function testing. HRCT scores were determined and compared to pulmonary function (FEV1, FEV1/FVC, and DLCO).
