Liver volume of 25 healthy adults was determined diagnostic ultrasound. With multiple images of longitudinalscanning by Picker 80 L grayscale B-mode scanner, volume of the liver was calculated by Carr's method. The averageliver volume was 1499 ml and the result was well corresponding to prior reports on liver volume by autopsy andother imaging methods.

Twenty two cases of extraarticular skeletal tuberculosis which showed unusual radiological features arereported and classifed into several categories with discussion on the differential diagnosis. Radiologicalpatterns of skeletal tuberculosis is so variable that with any kind of skeletal changes the possibility of theskeletal tuberculosis should not be excluded because of lack of its classical patterns.

Among the many causes producing lower back pain herniated nucleus pulposus and bulging disk have occupiedlarge percentaages and uniformly showed defect on lateral aspect of contrast filled thecal sac. But it isessential to differentiate each conditions from the other because of their different treatment methods.differentiation at metrizamide myelography between a diffusely bullging disk(unlikely to cause nerve rootcompression) and a herniated disk is based on the curature, extent, and multipllicity of the extradural deformityof the anterolateral margin of the contrast filled sac and o hte presence of fusiform widening of the most distalpart of the affected nerve root. The deformities caused by a bullging disk are round, usually symmetrical(aothoughoccasionally more prominent on one side), do not extend above or below the disk space, and can show multiple levelinvolvement; the nerve root is uniform in caliber and normal in size(although some of severe bulging show fusiformwidening of the most distal part of the affected nerve root). The deformities caused by a herniated disk isangular and extends cephalad and/or caudal to the level of the disk space; the affected nerve root is usuallywidened in its most distal visible part. A consecutive series of 50 patients with low back pain and no pasthistory of back surgery who did metrizamide myelography underwent spine CT and /or laminectomy. Using the criterialisted above for differentiation of bulging from herniated disk on metrizamide myelography, the myelographicdiagnosis was correct in 32(22 patients) of 34(24 patients) (95%) surgically and/or computed tomographicallyconfirmed bulging disks and in all 26 (100%) surgically and/or computed tomographically confirmed herniated disks.

It has been well known that the incidence of delayed or nonunion of tibial shaft fracture is high and in order to improve methods of treatment and to get satisfactory final results in these fractures, it is important to find out as early as possible whether the fracture is healing normally or not. The fracture healing is closely related to the circulatory conditions at the fracture site, however, in contrast to animal experiments it is impossible to visualize directly the circulatory conditions at the fracture site. There have been many efforts to visualize indirectly these vascular re-establishments through angiography. Kaski(1974) reported a paper concerning osteomedullography of tibial fracture with phlebocompression and noticed 5 types of veins related to the process of healing. We performed 54 cases of osteomedullography in 41 tibial fracture at 3 months after treatment and the following results were obtained: 1. The sinusoidal vein in the proximal fragment was observed most frequently and the next were intra-osseous crossing vein, periosteal callus vein, ascending branch of main efferent vein, and periosteal veins of proximal fragment in decreasig frequency. 2. The rate of positive finding in osteomedullography at 3 months after treatment was lower, and periosteal callus veins were observed more frequently in the group treated with only cast immobilization than in the group treated with plate and screws. 3. In the group treated with compression plate and screws, osteomedullographs were positive in all 3 cases within 3 months after operation and sinusoidal veins in the proximal fragment were visualized in all cases, however periosteal callus vein was not visualized at all. 4. After bone graft, the differentiation of periosteal callus from grafted bone was not easy in plain X-ray film, but osteomedullography was very useful in these cases. Positive findings were noticed in 2~3 months in all cases following bone graft. 5. The authors found that the ideal time of performing osteomedullography was 3 months following treatment. If found to be negative after 4 months following treatment, bone graft was necessary.
