The absence of soft tissue superimposition on bone makes CT greatly superior to conventional radiographs, even using special views, for demonstrating the hind foot. Views derived from both methods are compared. Semicoronary and transverse planes have been defined in relation to specific points in the tarsus. ⋯ In the transverse plane, the plantar talocalcaneal angle is 60 degrees to 70 degrees and the calcaneal-cuboidal angle is 20 degrees to 35 degrees. These values are based on measurements of 62 normal feet. They are valuable for judging quantitatively posttraumatic deformities, displacement of fragments and operative results.

We present three cases that illustrate the HRCT appearance of pulmonary lymphangioleiomyomatosis and pulmonary involvement in tuberous sclerosis. All patients had multiple cystic lesions diffusely distributed throughout the lungs. The lack of fibrotic changes was a prominent feature in all patients. HRCT correlated more closely than conventional CT with the pathologic findings.

The position of the supinator fat pad is regarded as a valuable sign in fractures of the elbow. In our patients the pad was visible in 277 out of 337 cases (82%). ⋯ There was marked variation in the distance between the pad and the radius, depending on age, build and projection. Our results indicate that the sign is not suitable for the diagnosis of fracture of the elbow.
