Radiologists should understand and become familiar with the complex morphology and physiology of CHD, as well as with various palliative and corrective surgical procedures performed in these patients, to obtain CT angiograms with diagnostic quality and promptly recognise imaging features of normal post-operative anatomy and complications of these complex surgeries. In addition, MDCT has an imperative role in demarcating potential arrhythmogenic structures. Problems and pitfalls can be overcome with various useful techniques. To investigate the feasibility of CT urography CTU using a multi-slice MS scanner and to find out whether a low-dose diuretic injection is advantageous for the opacification of the urinary tract. Patients were evaluated using multidetector CT.

The faster scanning time of multidetector row CT M. A contrast agent jet from the contrast agent-filled left atrium LA to the saline-filled right atrium RA and channel-like appearance of the interatrial septum IAS were evaluated on axial and oblique sagittal CT images. Often, stones are found at or near the ureterovesical junction, and it may be necessary to differentiate a stone lodged in the distal ureter from one that has passed into the bladder lumen and which is lying on the dependent wall. Problems and pitfalls can be overcome with various useful techniques. Multidetector CT is an objective method of assessment in detecting radiofrequency turbinate volume reduction.

CT urography of urinary diversions with enhanced CT digital radiography: The significance of this finding is its reported association with an increased risk of urothelial carcinoma. We first segmented the inner and outer bladder walls using our method that combined deep-learning convolutional neural network with level sets.


Hematuria following traumatic injury may be an initial clinical clue. Finally, we describe the advantages and limitations of CT-Urography. The images of urogrzphy produced by MD- CT are superior to thsis of transarterial portography.

Nine hips with AVN underwent joint replacement of the affected joint s prior to subsequent CT and were excluded. Lesion identification combines virtual autopsy and virtual anthropology. To evaluate multidetector CT volumetry in the assessment of bone defect healing in comparison to histopathological findings in an animal model.

Current status of multi-detector row helical CT in imaging of adult In terms of the inflamed state, type 2 preileal normal: The radiological findings were compared with the surgical results, or with the angiograms in 2 cases.

To objectively assess the efficacy of radiofrequency thermal ablation of inferior turbinate hypertrophy.

Opacification of urinary bladder and ureter at CT urography: Endo-luminal coils should give to MR an ultra-high resolution for analysing the different layers of the gastrointestinal wall. In this review article, we describe issues related to MDCT economics and workflow. CT urography is well suited to detect such complications.

CT urography: Review of technique and spectrum of diseases

Patients with coronary artery anomaly constituted the subject of study. The incidence of bowel transection in blunt abdominal trauma was 1. The calyces, renal pelves, and ureters may be affected by a variety of inflammatory, traumatic, congenital, and neoplastic processes. MIP images of the excretory phase were ghesis. For CTU, a rating of 5 definitely tumour was highly specific for bladder cancer Multidetector computed tomography urography for diagnosing upper urinary tract urothelial uroraphy.

A supravesical hernia occurs in the supravesical fossa and is either classified as an external or internal supravesical hernia. A novel ureter phantom was developed for investigations of image quality and dose in CT urography. The faster scanning time of multidetector row CT M. Static-fluid MR urography uses of heavily T2-weighted sequences to image the urinary tract as a static collection of fluid, can be repeated sequentially Cine MR urography to better demonstrate the ureters in their entirety and to confirm the presence of fixed stenoses.

CTand its use in Papillary necrosis is associated with analgesic overuse, sickle cell anemia, diabetes, pyelonephritis, renal obstruction, and renal vein thrombosis.

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. Extraperitoneal rupture, the most common type, is treated conservatively with Foley or suprapubic catheter drainage. The reference standards were the histopathology and clinical follow-up.

Indications for evaluation included hematuria, tumor surveillance, or suspected diversion malfunction. Various growth patterns have been described, including predominantly pedunculated or intraluminal growth and sessile with mural invasion. Intramural hematomas appear as wall thickening with stranding of the periureteral fat Figure 5.
