PURPOSE To evaluate the effect of MR contrast dose versus delayed imaging time on the detection of metastatic brain lesions based on lesion size. METHODS Contrast MR examinations with gadoteridol were obtained in 45 patients with brain metastases. The patients were divided into two groups: 16 received cumulative standard dose (0.1 mmol/kg) and 29 received(More)
BACKGROUND AND PURPOSE This study was an attempt to determine whether CT and MRI are comparable or if one is superior to the other in the early detection of ischemic stroke or hematoma. METHODS Patients with acute stroke were sought within 3 hours of onset for clinical examination and prospective evaluation by concurrently performed CT and MRI. Repeated(More)
The aim of this study was to investigate the relationship of glenohumeral anatomic measurements on MR imaging with supraspinatus tendon tears. The study was approved by the institutional review board and informed consent was obtained from each subject. Forty-two patients (mean age 55.5 years; age range 40–73 years) with supraspinatus tendon tears and 50(More)
RATIONALE AND OBJECTIVES This cooperative multicenter human study was designed to evaluate the safety, magnetic resonance (MR) imaging characteristics, and clinical response to a single gadolinium contrast agent: gadopentetate dimeglumine. MATERIAL AND METHODS Ninety-five patients (age range: 1 month to 78 years; sex: 50 males, 45 females) were included(More)
PURPOSE To investigate whether MR can provide additional information on fetuses with central nervous system abnormalities as demonstrated by ultrasonography. METHODS Fetal MR examinations were studied prospectively in 22 pregnant women whose fetuses showed evidence of anomalies on ultrasound performed in the High-Risk Obstetric Clinic. RESULTS In 19 of(More)
PURPOSE To study MR patterns of venous sinus occlusive disease and to relate them to the underlying pathophysiology by comparing the appearance and pathophysiologic features of venous sinus occlusive disease with those of arterial ischemic disease. METHODS The clinical data and MR examinations of 26 patients with venous sinus occlusive disease were(More)
OBJECTIVE The purpose of this study was to assess the MR and CT appearance of brain infection after bone marrow transplantation and to correlate the appearances with laboratory and pathologic findings. MATERIALS AND METHODS We retrospectively reviewed the records of seven bone marrow transplant recipients with radiologic evidence of brain infection. (More)
Tumors metastatic to the pituitary gland are uncommon, and they are difficult to differentiate radiologically from pituitary adenomas. We retrospectively reviewed the MR examinations and clinical records of nine patients with radiographic and/or clinical evidence of pituitary metastases. The most common clinical symptoms included cranial nerve deficits(More)
PURPOSE To evaluate the spectrum of MR characteristics of cystic acoustic schwannoma and to investigate its incidence. METHODS We retrospectively reviewed the MR findings and clinical records of 16 patients with cystic acoustic schwannomas. In addition, the MR examinations of 411 consecutive patients referred for clinical suspicion of acoustic schwannomas(More)
