To describe findings in, and the clinical course and outcome of, aortic dissection (dissecting aneurysm) caused by angiographic procedures. ⋯ Angiographers should be aware of this potentially serious complication. The extent and type of the aortic dissection can be determined with CT.

To determine the structures responsible for the left-sided indentation in right aortic arch (RAA) with aberrant left subclavian artery (ALSA). ⋯ The aortic diverticulum appears to be an important factor in the production of the left-sided esophageal defect in patients with RAA with ALSA.

One intact and one ruptured single-lumen implant were surgically placed in a rabbit. Magnetic resonance (MR) imaging was performed before and after surgical removal, and the ruptured implant was imaged after removal of the implant shell. Multiple curvilinear hypointense lines (linguine sign) were present in the MR images of the ruptured implant and of the implant shell alone immersed in saline solution but not in the image of the free silicone. The collapsed implant shell in a ruptured silicone implant does cause the linguine sign.

Dr Henry Garland: the man, the myth, the legend, and the legacy. Garland Lecture from the 1991 California Radiological Society meeting.
In a century of American radiology, a relatively small number of radiologists have emerged as unquestioned leaders of the specialty. One of those was L. ⋯ The Garland family has endowed an annual lecture at the meeting of the California Radiological Society. This essay is taken from the 1991 lecture, which was an assessment of Garland's significance.

Sensory motor cortex: correlation of presurgical mapping with functional MR imaging and invasive cortical mapping.
To describe a clinically useful application of functional magnetic resonance (MR) imaging--presurgical mapping of the sensory motor cortex--and to validate the results with established physiologic techniques. ⋯ Presurgical mapping of the sensory motor cortex is a potentially useful clinical application of functional MR imaging.
