PURPOSE We aimed to determine whether the C-arm computed tomography (CT) blood volume (BV) imaging of hepatic tumors performed with a new prototype software is capable of measuring the BV changes in response to hepatic arterial treatments and to validate these quantitative measurements with commercially available multidetector computed tomography (MDCT) perfusion software. METHODS A total of ...

To compare the visualization of cortical fractures, cortical defects, and orthopedic screws in a dedicated extremity flat-panel computed tomography (FPCT) scanner and a multidetector computed tomography (MDCT) scanner.We used feet of European roe deer as phantoms for cortical fractures, cortical defects, and implanted orthopedic screws. FPCT and MDCT scans were performed with equivalent dose se...

In the context of a multidisciplinary approach for the diagnosis and treatment of ovarian cancer, the contribution of radiology includes the following four fundamental points: identification of the lesion, its characterization, study of its extension and evaluation of its evolution. This article describes the findings and key diagnostic elements in MDCT (Multidetector Computed Tomography) and M...

Objective: The higher risk and fatality of cardiovascular disease in subjects with homozygous familial hypercholesterolemia warrants early screening. Computed tomography angiography is the most promising method at present as a reliable and reproducible noninvasive diagnostic test of cardiovascular disease. We aimed to describe the 64-slice multidetector computed tomography coronary angiography ...

Imaging plays a vital role in the evaluation of patients with suspected or proven peritoneal malignancy. Nevertheless, despite significant advances in imaging technology and protocols, assessment of peritoneal pathology remains challenging. The combination of complex peritoneal anatomy, an extensive surface area that may host tumour deposits and the considerable overlap of imaging appearances o...

PURPOSE To evaluate the potential of prospective electrocardiography (ECG)- gated 64-slice multidetector computed tomography (MDCT) for evaluation of myocardial enhancement, infarct size, and stent patency after percutaneous coronary intervention (PCI) with stenting in patients with myocardial infarction. MATERIALS AND METHODS Seventeen patients who were admitted with acute myocardial infarct...

conclusion our results indicate that dsct coronary angiography provides high diagnostic accuracy for the evaluation of cad patients during daily routine practice of a referral cardiovascular setting. background there are numerous studies that address the diagnostic value of dual-source computed tomography (dsct) as an alternative to conventional coronary angiography (cca). however, the benefit ...

OBJECTIVE To evaluate the efficacy of multidetector (16-row) computed tomography (MDCT) in imaging the upper and lower limb arterial tree in trauma and peripheral vascular disease. METHODS Thirty three patients underwent multislice computed tomography angiography (MSCTA) of the upper or the lower limb on multislice (16-slice) CT scanner between November 2004 and July 2005 in the Department of...

Hemoptysis is the expectoration of blood that originates from the lower respiratory tract. It is usually a self-limiting event but in fewer than 5% of cases it may be massive, representing a life-threatening condition that warrants urgent investigations and treatment. This article aims to provide a comprehensive literature review on hemoptysis, analyzing its causes and pathophysiologic mechanis...

OBJECTIVES To evaluate and compare surface doses of a cone beam computed tomography (CBCT) and a multidetector computed tomography (MDCT) device in pediatric ankle and wrist phantoms. METHODS Thermoluminescent dosimeters (TLD) were used to measure and compare surface doses between CBCT and MDCT in a left ankle and a right wrist pediatric phantom. In both modalities adapted pediatric dose prot...
