“…Abdominal compression was applied 10 to 15 minutes after the IV injection of contrast, and CT examination was begun 20 to 30 minutes after injection. 6 More recently, efforts have been made to view 3D CT images in patients with orthotopic ilioneobladders or ureteral iliorectosigmoidostomies. In a study of 54 patients with continent urinary diversions who underwent CT with 3D depiction of the reconstructed lower urinary tract, while no pathologic findings were visible that were not evident on conventional CT, the images suggested a useful role for 3D CT in the planning of lower abdominal surgery 7 or when there are unexplained findings and symptoms in patients with bladder substitutions.…”

The applications of three-dimensional (3D) CT techniques encompass a spectrum from calculus disease to preoperative planning. With proper selection of display windows and levels, accurate measurement of stone size can be achieved, along with volumetric information. A CT scan with reconstruction may help guide the direction of an endopyelotomy incision away from crossing vessels. The benefits of 3D CT in the evaluation of living renal donors include lower cost and decreased patient morbidity. In renal allograft recipients and other patients, the study may be used to investigate hypertension. Also, 3D CT is invaluable in planning nephron-sparing surgery for renal masses. The ultimate role of this modality rests in the hands of clinicians who can benefit from them and the radiologists who must provide the high-quality images and the interpretive expertise.

“…The preoperative planning is established on Spiral CT Urography [1]. The classical CT Urography is a succession of 3 or 4 CT acquisitions of the abdomen, the first performed with no intravenous contrast, the two or three next after an intravenous bolus contrast medium injection.…”

Anatomic study of the lumbar region applied to multiplanar imaging techniques: Importance and use of oblique vertical sections

et al. 1994

View full text Add to dashboard Cite

This anatomic study of the lumbar region (as defined by Rouvière [11]) applied to multiplanar imaging techniques was carried out both in the cadaver and in vivo. The cadaver study (5 cases) consisted of anatomic sections (transverse, sagittal, frontal and oblique) and computerised three-dimensional reconstructions after CT studies on subjects injected with colored and radio-opaque latex. The in vivo study (4 cases) used MRI sections and three-dimensional ultrasound sections coupled with the pulsed doppler. The spatially referenced oblique vertical sections revealed the structures from unusual aspects, situating them amidst the retroperitoneal area with the maximum of topographic landmarks. The transposition of these results (obtained by sectional anatomy of the retroperitoneal region) to the new techniques of multiplanar formatting after MRI, ultrasound or CT data acquisition should optimise the investigation of certain retroperitoneal structures by specifying the ideal planes of section for each organ, while diminishing certain artefacts specific to acquisitions in the traditional planes of section. Oblique vertical sections seem eminently suitable for ultrasound location of the suprarenal compartments, study of the renal pedicles and topographic retroperitoneal location. This oblique vertical visualisation constitutes a fundamental resource for the development of video-monitored surgical procedures as it corresponds exactly to the axes of the access routes in percutaneous surgery of the kidney and the adjacent anatomic structures.
