The linear-quadratic formula and progress in fractionated radiotherapyBritish Journal of Radiology - Tập 62 Số 740 - Trang 679-694 - 1989
J. F. Fowler
Clinical gains have been reported from the use of nonstandard fractionation
schedules planned with a radiobiological basis. Hyperfractionation provides the
leading example, as described below, with accelerated fractionation being
developed more recently. Although examples of almost every kind of fractionated
schedule can be found in the literature over the past 90 years, it is only
within the last... hiện toàn bộ
Fetal doses from radiological examinations.British Journal of Radiology - Tập 72 Số 860 - Trang 773-780 - 1999
Ernest Osei, K. Faulkner
There has been growing concern about radiation exposures in the case of pregnant
women who undergo radiological examinations of the lower abdomen and pelvis,
when the embryo/fetus is near or included in the X-ray field. This paper
describes a retrospective study of 50 pregnant women accrued over a period of 10
years. Most of these women were not aware of pregnancy at the time of their
radiological... hiện toàn bộ
Pregnancy after uterine artery embolization to control haemorrhage from gestational trophoblastic tumourBritish Journal of Radiology - Tập 69 Số 823 - Trang 624-629 - 1996
J. McIvor, Evan Wm. Cameron
Abstract Gestational trophoblastic tumour (GTT) of the uterus can cause severe
and even life threatening haemorrhage in patients who may be contemplating
future pregnancy. Three cases of successful pregnancy after uterine artery
embolization to control severe haemorrhage from uterine GTT are reported. Both
uterine arteries had been selectively catheterized and embolized in these
patients. The area... hiện toàn bộ
Risk of childhood cancer from fetal irradiation.British Journal of Radiology - Tập 70 Số 830 - Trang 130-139 - 1997
Richard Doll, Richard Wakeford
The association between the low dose of ionizing radiation received by the fetus
in utero from diagnostic radiography, particularly in the last trimester of
pregnancy, and the subsequent risk of cancer in childhood provides direct
evidence against the existence of a threshold dose below which no excess risk
arises, and has led to changes in medical practice. Initially reported in 1956,
a consisten... hiện toàn bộ
A survey of the radiation exposures received by the staff at two cardiac catheterization laboratoriesBritish Journal of Radiology - Tập 63 Số 755 - Trang 885-888 - 1990
Brian J. McParland, Josip Nosil, Brian Burry
Staff working in cardiac catheterization laboratories receive radiation
exposures from primary radiation (if any part of their body is placed within the
X-ray beam) or from secondary radiation due to scatter from the patient and
image intensifier and to leakage from the X-ray tube. As a result, the radiation
exposure distribution over a staff member's body is expected to be non-uniform.
