Diagnosis value of multi-slice spiral CT in renal trauma.
Computed tomography (CT) is most commonly used as a noninvasive approach in diagnosis of internal organ injures. Use of multi-slice spiral CT becomes more popular in diagnosis of trauma because of its ability to generate 3D volumetric information. This study evaluated the diagnostic value of multi-slice spiral computed tomography (MSCT) with enhanced scanning in renal trauma. In total, 126 pati...
متن کاملAdvanced single-slice rebinning in cone-beam spiral CT.
To achieve higher volume coverage at improved z-resolution in computed tomography (CT), systems with a large number of detector rows are demanded. However, handling an increased number of detector rows, as compared to today's four-slice scanners, requires to accounting for the cone geometry of the beams. Many so-called cone-beam reconstruction algorithms have been proposed during the last decad...
متن کامل[Diagnosis of plasma cell mastitis with multi-slice spiral CT].
OBJECTIVE To evaluate the diagnostic value of multi-slice spiral CT (MSCT) for plasma cell mastitis. METHODS Radiographs of MSCT for forty-six patients with plasma cell mastitis diagnosed by pathological examination were reviewed. RESULTS The findings of MSCT of plasma cell mastitis could be divided into four types, including the inflammation type, the abscess type, the sinus and fistula ty...
متن کاملAdvanced single-slice rebinning for tilted spiral cone-beam CT.
Future medical CT scanners and today's micro CT scanners demand cone-beam reconstruction algorithms that are capable of reconstructing data acquired from a tilted spiral trajectory where the vector of rotation is not necessarily parallel to the vector of table increment. For the medical CT scanner this case of nonparallel object motion is met for nonzero gantry tilt: the table moves into a dire...
