Image analysis methods for diagnosis of diffuse lung disease in multi-detector computed tomography
… of the onset and progression of the disease. Multidetector CT (MDCT) allows acquisition of volumetric datasets with almost isotropic voxels, enabling visualization, characterization and quantification of the entire extent of lung anatomy, thus lending itself to characterization of Interstitial …

Assessment of coronary artery plaque progression using 64 slice multi-detector computed tomography (MDCT)
… who had plaque detected on repeated 64-slice multi-detector computed tomography (MDCT) with a mean interval of 25 ± 10 months were enrolled in this retrospective study. Calcified plaque volume was measured using noncontrast calcium scoring CT. Non-calcified plaque volume was measured using …

Usefulness of Multidetector Computed Tomography Angiography in Vertebral and Basilar Artery Dissection
… (VBAD) is difficult to diagnose by conventional computed tomography. However, Multi-detector computed tomography (MDCT)angiography is not only a less invasive diagnostic technique than conventional angiography but also provides high quality images. We assessed clinical manifestations and …

Feasibility Study of Low Dose Chest CT for Initial Evaluation of Blunt Chest Trauma Patient
INTRODUCTION: Multi-detector computed tomography (MDCT) is now modality of choice for evaluation of the polytrauma patients including thoracic injury. However, the routine use of CT results in rapid increase of the CT radiation dose in blunt chest trauma evaluation. Therefore, according to the …

A Study of Imaging Techniques of 3-Dimennsional CT Diagnosis for Rib Fractures
… is not high and the use of axial CT images of multi-detector computed tomography make us to spend so much time and effort to detect rib fracture. Multidetector CT is increasingly used for the evaluation of trauma patients and 3-dimensional CT image is known to be effective to detect rib …

Comparative imaging of the canine acute abdomen: survey radiography, contrast-enhanced ultrasound and contrast-enhanced multi-detector helical computed tomography
… rapid and accurate diagnosis. Contrast-enhanced multi-detector computed tomography (CE-MDCT) is the current modality of choice for evaluating acute abdominal pain in people. In phase one of this study we hypothesized that CE-MDCT would be a feasible and safe technique for use in awake and lightly …
