A new device to support handicapped patients during venography or myelography.

The authors describe a seating device which holds the patient in position when the x-ray table is tilted and permits non-weight-bearing venograms to be obtained in handicapped as well as normal patients. Simultaneous bilateral venography reduces the study time considerably. The device is also helpful in lumbar myelography in paraplegics.

Unusual bone scan presentation in osteomalacia: symmetrical uptake--a suggestive sign.

Osteomalacia presents radiographically as deossification, coarsening of the trabecular pattern, and pseudofractures. Contrary to the usual bone scan manifestation of osteomalacia, consisting of a generalized increase in periarticular radionuclide accumulation and pronounced costochondral junctional uptake, this report describes an unusual bone scan presentation with negative radiographic studies showing only some deossification. Symmetric distribution of the focal lesions is considered a suggestive sign of osteomalacia.

Improved dynamic and static imaging of abdominal aortic aneurysms.

The authors describe a technique for rapid, convenient in vivo labeling of circulating erythrocytes with 99mTc and the application of this technique to the evaluation of abdominal aortic aneurysms. Dynamic perfusion images and equilibrium blood pool images were obtained in 9 patients with documented aneurysm, and 7 of them indicated an aneurysm on the radionuclide study.
