The purpose of this study is to assess the utility of CT paging arteriography with a multidetector -row CT as a replacement for conventional angiography in the evaluation of splanchnic arterial anomalies. L’avvento della TC multistrato e l’evoluzione delle tecniche di elaborazione consentono di ottenere dei quadri urografici ottimali comparativi con quelli convenzionali. Two independent radiologists considered PFO present if left atrial enhancement was detected visually before enhancement of the pulmonary veins or if an early peak of left atrial enhancement was found at time-attenuation curve analysis. The test AUCs were 0. Effect of CT threshold. Hematuria can signify serious disease such as bladder cancer, upper urinary tract urothelial cell carcinoma UUT-UCC , renal cell cancer or urinary tract stones. With ongoing improvements in computer-aided diagnosis CT colonography becomes an alternative to fiberoptic colonocopy for screening http:

Extraperitoneal rupture, the most common type, is treated conservatively with Foley or suprapubic catheter drainage. Using the MIP technique and an Advantage window voxtal 3. When physiologic saline solution was used instead of furosemide, the radiopacity inside the enhanced pelvicalices was times higher and more inhomogeneous. Comparing the two time periods, during which a software update was performed, a mean time reduction of 4: Six patients underwent multidetector -row CT duodenography before upper gastrointestinal endoscopy. Well-trained technicians, state-of-the-art workstations, and fast networking are the most important factors to improve workflow. There may be proximal dilatation if the ureteral lumen is narrowed.

Multidetector CT findings of bowel Transection in blunt abdominal trauma. In addition, we evaluate liver regeneration of both the donor and the recipient by serial volumetry. The number, size and course of the renal arteries and veins are easily identified by MDCT angiography.

Femoral head avascular necrosis: EDWP with regularized energies further propagates the conjoint contours to the correct bladder boundary. Multi-detector CT is an excellent diagnostic modality in bowel and mesenteric injury. To retrospectively evaluate the clinical feasibility of high-pitch excretory phase images during dual-source CT urography with Stellar photon detector.


Since the implementation of a MDCT scanner in April85 children 31 girls, 54 boys with a mean age of 9. Current status of multi-detector row helical CT in imaging of adult In the present study we describe the incidence and new CT signs of bowel transection in blunt abdominal trauma.

Congenital anomalies of the kidneys, including horseshoe kidney, renal ectopia with or without crossed-fusion,hypertrophied column of Bertin, and renal agenesis sometimes with a genesis or cystic dilatation of the ipsilateral seminal vesicleare all well depicted by CT urography. Diverticula are also predisposed to infection and development of urothelial tumors.

A consecutive series of patients over years of age, presenting with macroscopic haematuria and without urinary tract infection underwent same-day CTU, US, and flexible cystoscopy.

Histomorphometry served as the reference standard. Urinary bladder rupture may be seen in cases of pelvic trauma, although the recommended imaging method to detect a urinary bladder rupture is a cystogram, using direct instillation of contrast into the bladder and imaging with either conventional radiography or CT.

A data set of patients, 87 with wall thickening and 25 with normal bladders, was collected retrospectively with IRB approval, and split into independent training and test sets. This goal remains elusive due, in part, to lack of a noninvasive and accurate imaging study. Accuracy remained high AUC, 0.

Although most patients with blunt trauma urograpuy now treated nonsurgically, evolution in the understanding of spinal stability, as well as the development of cct surgical techniques and hardware, has driven management strategies that are increasingly favorable toward surgical intervention. To evaluate the lung parenchyma, bronchial branching pattern, and vascular anatomy, four series of images were systematically reconstructed as follows: The causes of pulmonary arterial hypertension PAH are diverse and include multiple congenital and acquired cardiac diseases as well as diseases primarily affecting the pulmonary vasculature, lung, pleura and chest wall.


Multidetector computed tomography is the modality of choice for identifying normal findings after surgery, postoperative complications, and tumor recurrence in patients who have undergone pancreatic surgery. What is the role of multidetector CT? CTU is an effective modality in the evaluation urograpby non-calculous urinary obstruction diseases.

multidetector ct urography: Topics by

CT urography is recommended as the initial imaging test for hematuria in patients at high-risk for UCC. False-positive lesions included periductal fibrosis, cystic change, duct papillomatosis, sclerosing adenosis, fibroadenoma, and others. Initial results with this new technique are encouraging. If the tumor obstructs a calyx, the calyx may appear irregular or amputated. Multidetector row CT for imaging the paediatric tracheobronchial tree.

Homogeneous enhancement of the kidneys during the nephrographic phase optimizes small renal mass detection. Currently, CT urographic evaluation of the urinary bladder generally is not considered accurate enough to exclude small superficial urothelial tumors, and cystoscopy is indicated for complete bladder evaluation.

CT urography: Review of technique and spectrum of diseases

One hundred five patients 57 men, 48 women; mean age, 53 years with a recent stroke underwent TEE and multidetector CT on the same day. While multi detector-row CT offers unparalleled speed urovraphy acquisition, spatial resolution, and anatomic coverage, a challenge presented by these advantages is the substantial increase on the number of reconstructed cross-sections that are rapidly created and in need of analysis.

Transesophageal cardioechography is urograpyh of the useful tools for detecting aortic arteriosclerosis causing aortogenic cerebral embolism.

The gadolinium-enhanced urine is visualized with fast T 1 -weighted 3D-gradient-echo sequences. The degree of opacification was scored as optimal or good in
