Thirty-four patients with a wide variety of benign and malignant incidental skull findings on routine magnetic resonance (MR) imaging of the brain were reviewed. In most instances detection of the lesions was not difficult. However, recognition of va

Retroperitoneal cystic lymphangiomas are uncommon tumors of the abdomen; CT and ultrasound have been used in the past to identify and characterize them. To the best of our knowledge the MR findings of retroperitoneal cystic lymphangiomas have not bee

• Periventricular white-matter lesions were visualized in the brains of elderly patients being assessed for possible Alzheimer's disease. The magnitude of these lesions, expressed as lesion-brain ratios, correlated closely with the severity of deme

Magnetic resonance imaging (MRI) was performed in 22 patients at various times (0-3) years) following radiation therapy to the spine. T1 and T2 weighted images were obtained at 0.5 Tesla. Increased signal was seen after 800-6000 rads (8-60 Gy). Marro

The T2 component of the magnetic resonance imaging (MRI) signal was measured in 11 brain loci in six elderly patients diagnosed as having probable Alzheimer's disease. T2 values and relative amount of periventricular high-intensity foci were signific

Postero-anterior radiographs and magnetic resonance imaging (MRI) of the chest were performed in nine biopsy proven cases of sarcoidosis. MRI was more sensitive than a postero-anterior chest roentgenogram in detecting hilar and mediastinal adenopathy

The Motion Artifact Suppression Technique (MAST) is a method which uses a series of gradient echos that are computed to cancel velocity, acceleration and pulsatility components of involuntary motion in MR imaging. A total of 916 patient studies were
