Echocardiography (ECHO) is useful to document changes in left ventricular mass (LVM) in groups of patients, but may be too variable for use in the individual patient. Magnetic resonance imaging (MRI) may be a more precise and reliable method to quantify the mass of the left ventricule. This study reports the accuracy, precision, and reliability of LVM(More)
A follow-up total-body I-131 scan in a patient with follicular thyroid carcinoma demonstrated radionuclide accumulation in the right hemithorax. Originally thought to be pulmonary metastatic thyroid carcinoma, the uptake region proved to be intrathoracic gastric mucosa. The patient had been treated for squamous cell esophageal carcinoma by(More)
Using gadolinium-DTPA enhanced MRI we analyzed the enhancement characteristics of palpable breast masses in 23 patients--10 cancers and 13 benign lesions. The most specific finding for separating benign from malignant lesions was a ratio of maximum intensity change divided by the time interval during which this first occurred. Designated ranges of this(More)
Fourteen patients (16 sites) with clinical and/or radiographic evidence of neuropathic osteoarthropathy (Charcot joints) were evaluated with combined indium-111-leukocyte (111In-WBC) and technetium-99m-methylene diphosphonate (99mTc-MDP) bone imaging for suspected osteomyelitis. Magnetic resonance (MR) images were obtained in seven patients. Using a(More)
Left ventricular mass (LVM) is an important consideration in the management of cardiac hypertrophy associated with hypertrophic cardiomyopathy (HCM), systemic hypertension, and other diseases. A brief MRI cardiac imaging procedure used to monitor regression of LVM during treatment would be beneficial in management of these patients, since echocardiograms(More)
We investigated the utility of bone marrow MRI for diagnosing marrow metastases from breast cancer compared with radionuclide bone scan, iliac crest marrow biopsy with histology and antibody immunostaining, and clinical follow-up. We report the results of 43 MRI studies in 32 patients and discuss the evolution and comparison of optimal MRI techniques. MRI(More)
Cryptococcosis, a potentially fatal pulmonary infection, rarely occurs in advanced form in immunocompetent individuals. Radiographic findings are variable and include single and multiple mass-like infiltrates, nodules, and segmental infiltrates. MRI manifestations of pulmonary cryptococcosis have not been reported previously. We have compared MRI, CT, and(More)
