摘要:

This second edition is an enlarged version of Volume 7 in the Medical Physics Handbook series. Much of the original text has been retained unaltered while several chapters have been expanded to take in new developments and to update the older techniques. The text is profusely illustrated—so very necessary in a book of this type—and the larger format of the book has enabled the text/diagram ratio on some pages to be improved. The reader, however, is still left turning on several pages to find the figure referred to in the text.

摘要:

AbstractA relationship has been demonstrated between nuclear magnetic resonance (NMR) longitudinal relaxation times (T1values) obtainedin vivoin both normal and oedematous (peritumoral) brain tissue, and measurements of brain water obtained by gravimetric analysis of operative samples. Significant correlations were found in seven patients in both cortex (r= 0.97,P<0.001) and white matter (r= 0.92,P<0.001). These findings suggest that NMR may prove a useful technique for monitoring brain oedema.

摘要:

This is a satisfactory monograph, especially in so far as it describes and illustrates, with beautifully designed and produced line drawings, the normal anatomy of the anterior inferior cerebellar artery (AICA) and related vessels.

摘要:

AbstractThe radiation dose to a series of adult and paediatric patients undergoing cardiac catheterisations and adults having percutaneous transluminal coronary angioplasty has been measured/determined directly using lithium fluoride thermoluminescent dosemeters and indirectly using an air ionisation chamber which indicated exposure-area product. Somatic and genetic risks are estimated from the dosimetry results. It is suggested that the magnitude of the radiation hazard is negligible compared with other clinical hazards associated with these procedures.

摘要:

The authors of this small paperback book have made a valiant attempt to survey the whole subject of cardiac ultrasound in less than 100 pages. The book is well produced and there are many good illustrations. All relevant major disease categories in cardiology are mentioned but, in some cases, the mention is little more than a listing.

摘要:

AbstractA method for increasing the sampling frequency of digital Xray systems is described. The method employs discrete, stepwise magnetic deflection of the focal spot and the recombination of the resulting displaced images. The technique was applied to a GE CT/T 8800 scanner operating in “Scout View” mode. The hardware and software modifications were minor. The transverse resolution was shown to improve from 0.63 to 0.9 line pairs per mm, using a test phantom. The effect of the improvement in resolution is also illustrated in the human. The possibility of further improving the resolution of the system is discussed.

摘要:

This is a small handbook that will be of very substantial value for trainees in radiotherapy. Its subsidiary title, “Royal Marsden Hospital Practice”, makes its contents clearer: it is a “recipe book” giving brief but essential details of the way most cancers are treated by radiotherapy at the Marsden. There is an 18-page introductory chapter, of which about 10 pages are taken up by illustrations, diagrams and talks, and the whole book is generously provided with these.

摘要:

AbstractA randomised pilot study is reported of d(15) + Be neutrons compared with 4 MV photons in the treatment of patients with astrocytoma. Sixteen patients were treated by photons and 18 by neutrons. Both treatments were well tolerated by patients. The median survival after photons was 11 months and after neutrons, 7 months. It was demonstrated that four of nine patients treated by neutrons had evidence at autopsy of radiation-induced brain damage. All had residual cancer. No patient treated by photons had signs of radiation-related morbidity. The trial was, therefore, discontinued prematurely.

摘要:

The incidence of carcinoma of the bronchus has now reached epidemic proportions in many Western countries. While the mortality rate for males with this disease has shown a small decline in recent years, this has been balanced by a steady increase in women such that, in the USA at least, lung cancer now ranks alongside breast cancer as the leading cause of death from malignant disease.

摘要:

AbstractA randomised trial is reported of mixed-schedule (neutron/photon) irradiation compared with photon therapy for patients with Grade III or Grade IV astrocytoma. Thirtyone patients were allocated to be treated by the neutron/photon regime and 30 patients by photons. The median survival was 4 months in the mixed-schedule group and 8 months in the photon group. The survival rates were not significantly different. All patients who died had evidence of residual brain tumour. None had signs of radiation-related morbidity.
