Background: One of the means of assessing dose to patients from Computed tomography (CT) procedure is through the determination of the skin entrance dose (ESD) with the appreciation of the concern that ocular exposure effects from CT scan includes possible induction of cancer and cataract. Due to the relatively more recent introduction of CT scans, little work has been done in this area in the ...
High resolution yttrium-90 ((90)Y) imaging of post-radioembolization microsphere biodistribution may be achieved by conventional positron emission tomography with integrated computed tomography (PET/CT) scanners that have time-of-flight capability. However, reconstructed (90)Y PET/CT images have high background noise, making non-target activity detection technically challenging. This educationa...
Objective To identify pulmonary thromboembolism (PTE) using the thrombus attenuation value on unenhanced computed tomography (CT).
This second edition atlas presents 166 cases. Purchasing the book also entitles you to 12 months’ access to further cases online. The book is divided into 14 sections covering all the expected areas of imaging including 23 positron emission tomography/computed tomography (PET/CT) cases, 11 cardiac cases including single-photon emission computed tomography (SPECT) and PET, and a section on radio...
BACKGROUND Medical X-rays are the largest man-made source of public exposure to ionizing radiation. While the benefits of Computed Tomography (CT) are well known in accurate diagnosis, those benefits are not risk-free. CT is a device with higher patient dose in comparison with other conventional radiation procedures. OBJECTIVE This study is aimed at evaluating radiation dose to patients from ...
