Therefore, whole-body low dose CT (WBLDCT) has been incorporated in the latest diagnostic criteria of the IMWG. The purpose of this study was to evaluate the role of WBLDCT in the early identification of patient
however, take days to provide the diagnosis, and false negative rate is relatively high. Imaging, in particular chest computed tomography (CT), can assist with diagnosis and assessment of this disease. Nevertheless, it is shown that standard dose CT scan gives significant radiation...
First, we wanted to show how to use low-dose CT in patients with suspected renal colic in current clinical practice. Second, we wished to discuss the different ways of reducing CT radiation dose by considering both behavioral and technological factors. Among the behavioral factors, limiting the ...
Low-dose chest CT scan protocol The image acquisition and analysis for the ImaLife study has been previously published30. ImaLife participants undergo a two-part low-dose CT using a third-generation dual- source CT scanner (SOMATOM Force, Siemens Healthineers, Germany). Firstly, participants under...
full potential of cardiac CT to impact disease detection, patient outcomes and healthcare economics, it is essential to apply dose reduction strategies through a patient-centric approach. In this manner, radiation exposure and image quality are optimized, while a patient’s radiation risk is ...
Low-dose contrast-enhanced chest CT exam Subjects will undergo a low-dose contrast-enhanced chest CT exam with coverage from the neck base through the lungs to the upper abdomen on a third-generation dual-source CT scanner as part of their routine clinical visit based on current guide...

We will evaluate the performance of the suggested approach by applying it to noisy simu- lated projections and low-dose projections acquired from a micro-CT scanner. Methods Given a noisy image, v, the goal is to find an image u that ideally preserves all important features in the image ...
2.2. CT examinations All CT examinations were performed on a 16 detector-row CT scanner (Aquilion 16; Toshiba Medical Systems, Otawara, Tochigi, Japan). The patients who were registered in the study underwent both standard dose CT and low dose CT examinations. Whole chest was scanned with a ...
MDCT comprehensive protocol (calcium score, stress CTA/CTP, rest CTA/CTP, and CTDE) was calculated by the method proposed by the European Working Group for Guidelines on Quality Criteria in CT: product of the chest coefficient (0.014) and the dose-length product obtained during each scan (19...
