Abstract Background Urinary bladder tumors are the most common type of detected in patients with gross hematuria. Multidetector computed tomography (MDCT) is an accurate method for detecting lesions. This review aims to describe features MDCT and possible values distinguishing these lesions bladder. Main body In this review, we discuss role evaluation cancer a broad spectrum lesions, including ...
Given the steep trajectory of evolution in multidetector CT technology and its complexity, dose reduction efforts require knowledge of interplay between CT scanning parameters and their impact on radiation dose and image quality in CT examinations. We describe the effects of modifying primary scanning factors such as tube current, tube potential, and pitch factor (applicable to helical CT scann...
We herein report two cases of incidental finding of the sternalis muscle in the right anterior chest wall on multidetector-row computed tomography (MDCT). We emphasize the diagnostic utility and value of additional postprocessed MDCT images, which can be easily created using volume data sets of MDCT, in establishing an accurate diagnosis of the sternalis muscle, an uncommon muscular variant.
Acute aortic syndrome can be due to acute aortic dissection, intramural hematoma, penetrating atherosclerotic ulcer, or unstable thoracic aneurysm. These life-threatening conditions are clinically indistinguishable, often presenting with acute chest pain. Contrast-enhanced, cardiac-gated multidetector computed tomography (CT) is a highly accurate imaging method for determining the cause of acut...
Fig. 1. Transthoracic Doppler echocardiography revealing severe obstruction of themechanical valve (A). The cause of obstruction could not be visualised by trans-oesophageal echocardiography (B). Multiplanar reformatted images on contrast-enhanced 64-slice multidetector CT clearly depict a circular mass (arrows) with high HU values involving both atrial (C) and ventricular (D) sides of mechanic...
A 7-month-old white female with Pentalogy of Cantrell was imaged using 64 slice multidetector computed tomography (MDCT) with 3D mapping to better determine the extent of cardiac, thoracic, and abdominal malformations. Complimentary to ultrasound, the use of 3D 64 slice MDCT can facilitate effective diagnosis and treatment planning in cases of Pentalogy of Cantrell.
Intestinal lipomatosis also known as lipohyperplasia is a rare disease. Diffuse infiltration of the fatty tissue mainly in the submucosal layer is characteristic. It is usually asymptomatic and found incidentally. We report a case of lipomatosis in the terminal ileum and ileocecal valve. Multidetector computed tomography (MDCT) with contrast enhancement showed fatty infiltration of the terminal...
To reduce the transfer load of the digital pulse shape acquisition systems applied to the large area telescope of the 4π-multidetector CHIMERA, we have tested an architecture based on a new sampling ADC-board equipped with two TigerSHARCs, a new generation digital signal processor, and able to perform on-board the Event Parameter computation. In this contribution we present the preliminary resu...
