We used magnetic resonance (MR) to image the bone marrow of 31 patients with lymphoma. Images were obtained of the femoral, pelvic, and vertebral marrow with a 0.15 tesla imaging system using a T1-weighted spin echo sequence (TR600/TE 40). With this pulse sequence, normal marrow produces a high intensity signal that reflects the presence of marrow fat(More)
The medical literature has emphasized that aspiration of gastric contents or oral bacteria is a common cause of aspiration pneumonia. Swallowing disorders have been implicated in this disease but not studied at the time that aspiration pneumonia was diagnosed. A significant difference was found in the incidence of videofluoroscopically confirmed(More)
Unenhanced T1- and T2-weighted spin-echo, short inversion time inversion recovery (STIR), and gadolinium-DTPA (Gd-DTPA)-enhanced spin-echo and STIR imaging techniques were used in 20 patients as part of a multicenter study to assess the safety and efficacy of Gd-DTPA in spinal imaging. Five patients had normal MR scans. Of those with lesions, both(More)
Previous attempts to characterize the estrous cycle of elephants have yielded conflicting estimates of cycle length and LH profiles. In order to establish artificial breeding programs in this species, resolution of these issues is needed. Therefore, four female African elephants housed at the Indianapolis Zoo were studied for approximately 6 mo beginning in(More)
The severity and persistence of corticosteroid-induced obesity were evaluated retrospectively in 23 children aged 1-14 yrs requiring more than 60 days of therapy with prednisone for idiopathic nephrotic syndrome. Mean relative weight (after clearing of proteinuria) at initiation of therapy was 107 +/- 10 percent. Peak relative weight on therapy was 119 +/-(More)
The sensitivity of MRI to marrow infiltration together with the ability to perform multiplanar imaging allows evaluation of the bone marrow in a manner that has never been feasible before. The clinical impact of this has yet to be fully realized. However, detection of focal marrow infiltration by MRI with concurrently normal conventional imaging studies has(More)
Magnetic resonance imaging (MRI) of the bone marrow was performed in 29 patients with leukemia, aplastic anemia, or lymphoma who were scheduled for bone marrow transplantation, and in 12 normals. T1-weighted coronal images (TR600/TE40) of the pelvis and proximal femurs demonstrated marrow pathology in adult patients. A simple MR grading system was developed(More)
Magnetic resonance (MR) imaging, performed on 31 women with 40 surgically proven adnexal masses, was reviewed to determine whether MR can distinguish hemorrhagic from nonhemorrhagic masses. Fourteen masses proved to be hemorrhagic at surgery including functional ovarian cysts (seven cases), cystadenoma (one case), endometriomas (three cases), hematosalpinx(More)
