Children have a higher chance of being contaminated by radioactive materials during a radiological or nuclear (RN) emergency. They are more sensitive to radiation health effects and suffer more significant psychosocial impacts than adults during emergency response. This paper presents a summary of recommendations on effective management of children during an RN emergency. These recommendations ...
OBJECT Large cerebral arteriovenous malformations (AVMs) are often not amenable to direct resection or stereotactic radiosurgery (SRS) treatment. An alternative treatment strategy is staged endovascular embolization followed by SRS (Embo/SRS). The object of this study was to examine the experience at Washington University in St. Louis with Embo/SRS for large AVMs and review the results in earli...
BACKGROUND Transarterial chemoembolisation (TACE), having demonstrated survival benefits, is the treatmentof choice in intermediate-stage hepatocellular carcinoma, although there is great heterogeneity in its clinical application. MATERIAL AND METHODS A survey was sent to the Madrid Regional hospitals to assess applicability, indications and treatment protocols. The assessment was made overal...
There is a growing concern about the transmission of bloodborne pathogens during medical procedures among health care workers and patients. Over the last three decades, radiological services have undergone many changes with the introduction of new modalities. One of these new disciplines is interventional radiology (IR) which deals with procedures such as arteriography, image-guided biopsies, i...
acid In the terminal stages of renal failure, renal trans plantation has become an effective means of treat ment (1,2) . Although survival rates have improved since the availability of adequate immunotherapy, present means of diagnosing the various forms of renal complications leave much to be desired. Since 1966 180 kidney transplantations have been performed at the university clinics in Munic...
The case of a 79-year old man who was suspected to have an insulinoma is presented. Although clinically and biochemically an insulinoma was the most probable diagnosis there was no supportive radiological evidence. Open surgery and exploration revealed a lesion which was confirmed to be an insulinoma. The patient's hypoglycaemia improved immediately following surgery. In the Sri Lankan setting ...
We report a case of a 45-year-old man with a complaint of both leg weakness and hypoesthesia. Radiological evaluation revealed an osteolytic lesion of the ninth thoracic vertebra. The patient underwent posterior corpectomy with total excision of the tumor, mesh cage insertion with posterior screw fixation and subsequent radiotherapy. Histology confirmed the diagnosis of Langerhans cell histiocy...
The incidence of neuroendocrine tumours of the gastroenteropancreatic system seems to have increased during the past decade. New diagnostic and therapeutic procedures have aroused the interest of physicians, though most see very few cases of such diseases. A group of members of the Nordic Neuroendocrine Tumour Group decided to compile some guidelines to facilitate the diagnosis and treatment of...
Background: Hysterosalpingography (HSG) is an indispensable tool for diagnosing infertility in females. The procedure exposes female reproductive organs to ionizing radiation as the genitals are irradiated during the process. Investigating patient absorbed dose during the procedures is essential for effective radiological protection of the patient. Objective: This study aims to investigat...
Introduction Due to the increasing use of angiography procedures and the higher risk of deterministic and stochastic effects for radiation workers of these sections than other radiological procedures, radiation safety is very important in angiography staff. So, this study aimed to obtain the effective dose of angiography staff and compare them with the standard dose limit and finally outline th...
