摘要:

This recent addition to the useful NCRP report series was prepared by a committee of leading American experts in the field. The report progresses through the various stages involved in tritium analysis, with sections on sample collection, sample preparation, measurement techniques and finally standardization and calibration.

摘要:

AbstractScintigraphy of the adrenal gland with131I—19-iodocholesterol has recently been added to radiological techniques in adrenal imaging and has been used successfully to demonstrate anatomical and functional disorders of the adrenals in a variety of clinical situations. A review of the authors' experience stresses the diagnostic value of this method. Radiological findings and results of scintillation imaging are complementary: their comparison improves and clarifies indications for scintigraphy.Hyperadrenal cortical diseases always gave satisfactory scintigrams, the most interesting results being obtained in adrenal cortical hyperplasia and unilateral hyperfunctioning adenomas. In these cases the evaluation of the response to stimulation or suppression tests was very useful. On the other hand scintigraphy was less valuable in demonstrating malignant and non malignant tumours.

摘要:

AbstractPhoton absorptiometric measurements of the right lower femur were carried out at regular intervals of one to three months in 58 recipients of renal transplant.(1) During the first six months after transplant, 57% showed a significant and abnormal rate of loss of bone mineral (mean 11.7% per year. ±1.1% S.E.M.) while 30 months' after transplantation only 17% showed such a significant loss (p=0.025).(2) Eighteen months after transplantation both male and female recipients of transplants had a significantly lower mean bone mineral index than controls (p<0.001).(3) Male patients who developed new post-transplant fractures had a lower mean bone mineral content compared with age and sex-matched controls taken from transplant recipients without such fractures (p<0.01). Similarly male patients with post-transplant fractures had a significantly longer mean period on regular haemodialysis (p<0.05) compared with patients without such fractures.Regular photon absorptiometric measurements provide an accurate, informative and non-invasive technique for following changes of bone mineral content after successful renal transplantation.

摘要:

This volume is a reprint of articles which appeared originally in Seminars in Nuclear Medicine (one chapter from January 1974, the remainder in the October 1975 issue). It represents the integrated concept in diagnostic imaging, the emphasis being on the relative value of the two techniques from a clinical standpoint.

摘要:

It is well-known that large squamous carcinomas in the mouth have a low cure rate with conventional radiation treatment. Attempts may be made to improve this situation by implantation of sources or treatment with an intra-oral cone, but as these may be difficult to control applicators are often preferred.The conventional oral radium applicator is uncomfortable for the patient to wear and is associated with considerable exposure to staff. In addition, the high energy γ rays are difficult to screen and radiation tolerance under these circumstances may be reached, not by the tumour and its immediate structures, but by normal tissues in the neighbourhood. Maximum screening of associated normal tissues can be achieved by using125Iodine, a radioisotope which emits X and γ rays of 27–35 keV. This is available in seeds which are useful for the manufacture of small or large applicators (Sealyet al., 1976) and which are acceptable to patients because of their light and elegant form.

摘要:

Percentage depth-dose tables are generally not available for non-square fields. To accommodate rectangular beams, tables of so called equivalent squares are utilized. Such a table is included in TheBritishJournal ofRadiology, Supplement 11 (and its predecessor, Supplement 10) for use in cobalt teletherapy. The table in Supplement 11 was generated using the mathematical methods of Clarkson (1941) and Meredith and Neary (1944). It was experimentally tested by Kemp and Burns (1958) on the then new Picker C3000 cobalt unit at the London Hospital and has served well ever since.

摘要:

In an earlier technical note (Payne, 1974), some of the problems associated with the implantation of iridium-192 wire were pointed out and a technique was described which minimized them.The basic implantation technique is as described by Pierquin (1964), Pierquinet al. (1971) and Paine (1972); a 1.2 mm bore nylon tube is threaded through the area under treatment to provide a pathway for a radioactive iridium-192 wire. The wire, which is itself inside a fine nylon tube for strength, and the outer tubing are fixed in the patient by crushing a lead or steel washer onto them.One of the suggested improvements to this method made by Payne (1974) involved the use of a block and pin system. The nylon tube is prevented from slipping through the wound by a block and pin which does not crush the tube, so that a clear path is left through it.

摘要:

The various syndromes resulting from an abnormal proliferation or neoplasia of mature plasma cells or their immature precursors constitute the plasma cell dyscrasias. These may present as multiple myeloma (plasma cell myeloma), solitary myeloma, extraosseous plasma cell myeloma, or plasma cell leukaemia.We have encountered an unusual case of multiple myeloma in which a patient previously diagnosed by bone biopsy and immunoelectrophoresis, developed multiple non-obstructing polyps of the small intestine and at the oesophagogastric junction. On biopsy, these lesions had the classical histopathology pattern of multiple myeloma. This is the first case of myeloma polyps of the small intestine to be reported in the radiological literature.A 72-year-old white female was admitted in 1972 with a painful mass in the mandible which was diagnosed as myeloma. Two years later, a mass in the right gluteal area appeared. This was biopsied, diagnosed as myeloma, and treated with radiotherapy. In May, 1974, she was readmitted for evaluation of vague abdominal pain, nausea and vomiting, and for treatment of heart failure and hypertension. There was no evidence of gastrointestinal bleeding.

摘要:

Congenital dilatation of the intrahepatic bile ducts (Caroli's disease) was first reported in 1958 (Caroliet al.) and is usually diagnosed late in the patient's illness and seldom before operation (Wattset al., 1974). Goddard (1974) could only find 16 previous case reports of the disease which attests to its rarity. Caroli (1968) has classified congenital intrahepatic cystic dilatation into two groups: first, a pure form not asociated with hepatic cirrhosis or portal hypertension and second, a type associated with congenital hepatic fibrosis. There is probably some overlap but Wattset al.(1974) consider most cases belong to the first group. The radiological diagnosis of Caroli's disease has, in the past, proven difficult. None of the 15 cases collected by Mujahedet al.(1971) were diagnosed before surgery. With improved modern techniques in organ visualization, the pre-operative diagnosis has become easier and we report the following case which was confidently diagnosed by ultrasonography and confirmed by transhepatic cholangiography, thus rendering invaluable assistance to the surgeon.A female of 19 years was first admitted to hospital in December 1975 because of increasing jaundice and rigors. Her clinical history was unremarkable except for her occupation as an assistant in a hospital sterilizing department and handling liver biopsy packs. Her total bilirubin was 5 mg% (conjugated level 3.8 mg%) and her alkaline phosphatase was 132 international units.
