Estimated average dose calculated from phantom study was 0. MR pyelography can rapidly and accurately depict the morphological features of dilated urinary tracts with information regarding the degree and level of obstruction, without using contrast medium or ionizing radiation. Renal cell carcinoma usually leads to a solitary pancreatic metastasis, whereas multiple pancreatic metastases are uncommon. Today, VUS is able to accurately assess the grade of reflux and the state of the urethra, previously considered fundamental limitations to the extensive use of this technique. Recent advances in tissue-harmonic and contrast-specific imaging techniques, together with the development of second-generation contrast agents, have improved the potential of ultrasonography both in the diagnosis and grading of VUR in children. US monitoring of the bladder, of the retrovesical space and of the kidneys was performed using, alternatively, both tissue-harmonic and contrast-harmonic modes. The two protocols were compared regarding the following points:
The aim of this study was to demonstrate the ultrasonographic features of prenatal bilateral torsion of the testis, and its histological correlation and management. We discuss the advantages and limits of VUS with respect to radiographic and radionuclide imaging in the light of an analysis of the most recent literature, and we described the new VUS study technique using second-generation contrast media. Location of stress injuries, types of bone alterations, and presence of periosteal and bone marrow edema were evaluated. Prenatal ultrasound has then a definitive role in detecting an obstructed genital tract. Imaging of the normal posterior urethra was skilfully demonstrated with US in 15 young boys with VUR.

Plain radiography has a low sensitivity but may reveal tibial stress fractures, bone tumors, and soft-tissue calcification.
We evaluated the distance between the TMJ disk and the mandibular nerve at the oval foramen level.
CT tenico from the 5 cm below the level of ureteral obstruction as demonstrated by MRU were selected out. The CT scans demonstrated unilateral involvement of the vidian nerve in 9 patients.

Significant difference in detection of early tibial stress injuries was found between MR imaging and both CT and bone raadiologia McNemar test; P. Pancreatic metastases are rare.
We present US and CT findings of a pancreatic tail pseudocyst extending into the subcapsular space of the left kidney. From to October 30,we studied 59 expansive renal lesions 28 malignant, 31 benign in 48 patients mean age 55 years, range with power Doppler US before and after the administration of an echo-enhancing agent Levovist, Schering AG, Berlin, Germany.
The aim of our paper is to review the role of ultrasonography in the diagnosis of VUR, from the initial experiences up to the recent use of second-generation microbubbles combined with contrast-specific low-mechanical-index software.
All of the subjects were informed about the study procedure. Combined magnetic resonance urography and targeted helical CT in patients with renal colic: The aims of this article are to describe the findings of perividian tumor spread and to compare the accuracy of MRI and CT in diagnosing perineural metastasis along the vidian nerve.

One hundred and fifteen patients, with variable degree of hydroureteronephrosis demonstrated by US and urography were subjected to MR pyelography obtained by means of two ultra-fast sequences. Intrahepatic portal vein aneurysm: Growing requests by paediatric nephrologists and surgeons require that even general radiologists become familiar with this technique.
The two protocols were compared regarding the following points: Today, VUS is able to accurately assess the grade of reflux and the state of the urethra, previously considered fundamental limitations to the extensive use of this technique. Harmonic US imaging of vesicoureteric reflux in children: Ultrasonographic features, histopathological findings and management. Dirigente medico Responsabile medico della Risonanza Magnetica dell’U.
Moreover, a diagnostic algorithm in patients with chronic lower leg pain is proposed.
Neuropathic pain in temporomandibular joint disorders: The presence of a fluid-debris level inside the cystic anechoic mass must be considered a crucial finding. Sensitivity in detecting stones, strictures and congenital tecnicl junction obstructions was respectively A case of bilateral prenatal testicular torsion: Plain radiography has a low sensitivity but may reveal tibial stress fractures, bone tumors, and soft-tissue calcification.
Colour Doppler US examination was performed. Histology showed recognizable seminiferous tubules and Leydig cells. Eighty consecutive children were prospectively studied with contrast-enhanced second-harmonic VUS. Protocol B consisted of the entire unenhanced helical CT of the urinary tract.
Ten patients met the selected criteria for perineural metastasis, gadiologia was bilateral in 3 patients, with a total of 13 vidian metastases. Epub Apr Power Doppler US showed vascular structures in 34 patients.
McNemar test was used to detect statistically significant differences. We identified 5 patterns of vascular architecture of the lesions, both before and after contrast agent administration, following the classification by Jinzaki e Coll.
