CT UROGRAPHY THESIS

We wanted to determine the role of multidetector row CT for the evaluation of the sacroilitis in patients with ankylosing spondylitis. The utility of 64 channel multidetector CT angiography for evaluating the renal vascular anatomy and possible variations: In addition, 23 patients who underwent both modalities were compared Student t test and linear regression analysis. Therefore, the behavior of noise versus pitch returns to the single detector row paradigm, with noise being independent of pitch. The optimum diagnostic imaging strategy for patients with hematuria at high-risk for UCC involves the use of CT urography as a replacement for other imaging tests ultrasonography, intravenous urography, or retrograde ureteropyelography and as a triage test for cystoscopy, resulting in earlier diagnosis and improved prognosis of bladder cancer, UUT-UCC, renal cell cancer and stones. To analyze the task-specific variable costs combined with the diagnostic effect of MDCT and IVU for patients with acute flank pain, and to determine which is most cost effective.

According to patient gender, type 1 male: This group of patients may show non-calcified plaques as the first sign of their coronary artery disease. The findings recorded in this study indicate that noninvasive preoperative planning with row multidetector CTA and CTU is a reliable ‘one-stop shopping’ method of examination for potential living kidney donors. Intravenous contrast is administered and, following a to sec delay, scanning of the abdomen and pelvis is performed during the nephrographic phase. Unfortunately, regarding duplex kidney with prolonged dilatation, the affected parenchyma and tortuous ureters demonstrate a lack of or delayed excretory opacification. Among the 48 children with tracheal bronchus, 45 had right-side tracheal bronchus and 3 had bilateral tracheal bronchi with heterotaxy syndrome. Inadequate preparation of the patient, weaknesses into the protocol, gaps and errors in interpretation are responsible for false positive and false negative results.

Infiltrating urothelial carcinoma tends to invade the renal sinus fat and renal parenchyma as a soft tissue neoplasm of decreased attenuation compared to that of the normal kidney, usually without a significant change in the renal contour Figure 8.

Follow-up information was received in We identified two main types of ACB: Contrary to the common assumption that the retrocecal appendix is the most common position, the in vivo appendix is seen more often on MDCT in the subcecal and deep pelvic positions. Multidetector computed tomography urography for diagnosing upper urinary tract urothelial tumour. Duplex kidney could not be confirmed on typical four-phase CTU, whereas it could be easily diagnosed in axial and CT -3D reconstruction using prolonged CTU prolonged-delay phase.

In case of delayed excretion of contrast by the cct, the delayed CT scans were obtained at minutes after contrast injection.

CT urography: Review of technique and spectrum of diseases

The purpose of this pictorial essay is to illustrate MDCT angiographic appearance of normal anatomy and common variants of the renal vasculature. Urogralhy necrosis is associated with analgesic overuse, sickle cell anemia, diabetes, pyelonephritis, renal obstruction, and uroography vein thrombosis. To evaluate the utility of slice MDCT in children with tracheal bronchus and to characterize the frequency of tracheal bronchus in children with congenital heart disease.

In 17 patients a rupture of the globe was diagnosed during surgery. Some of these structures and landmarks include the right SAN artery, right atrial cavotricuspid isthmus, Koch triangle, AVN artery, interatrial muscle bundles, and pulmonary veins.

Evaluation of secondary spontaneous pneumothorax with multidetector CT. Compared with conventional angiography, reader A correctly evaluated the hepatic arterial anatomy depicted at three-dimensional CT angiography.

CT urography for hematuria.

Negative predictive value NPV was 0. The CT derived Spigelman score based on maximum polyp size was accurate in all five patients.

Furthermore, MS-CTU can be combined with low-dose furosemide for accelerated passage of excreted contrast material obviating the need for abdominal compression. The study was approved by the institutional review board, and informed consent was obtained from all patients. ECG-gated- multidetector CT is a non invasive modality. CT is nowadays a modality of choice for digestive imaging. The CT densities of different concentrations of contrast media and contrast-to-noise ratio were significantly higher when urrography voltages 90 kV versus kV, kV versus kV were applied.

With enhanced CCP, those values were Multidetector CT technology, in combination with interactive manipulation of the raw dataset, can be useful in the creation of multiplanar reconstructed images and in the identification of a venous injury caused by blunt trauma.

Fifty-three patients with clinically suspected VA were enrolled in this study. CT portography by multidetector CT provides excellent images in the visualization of portosystemic collaterals. All 7 cases had isolated and tortuous arterial anatomy from the descending thoracic c to the basal segment of the left lower lobe; however, variable distribution of branches was observed.

CT -CTA could accurately demonstrate vascular anatomy and capture the earliest stages of mesenteric ischemia in a porcine model. MDCT is a reliable imaging technique for the diagnosis of tracheal bronchus.

False-positive lesions included periductal fibrosis, cystic change, duct papillomatosis, sclerosing adenosis, fibroadenoma, and others.

CT urography for hematuria.

Comparative identification, the comparison of ante- and post-mortem imaging data, can be performed on both teeth and bones. No shunt was seen in patients without a flap valve.

Twenty patients 39 UUT excreting units were evaluated. The relative incidence of various positions of the appendix found in all of our study patients was: Two radiologists analyzed the stenosis degree, presence or absence of plaque, plaque composition, and a remodeling index of the related-segment in CAG with an EG test, which were used as a gold standard.
