Relevance of magnetic resonance imaging-detected pelvic sidewall lymph node involvement in rectal cancer.

Background: The significance of magnetic resonance imaging (MRI)-suspected pelvic sidewall (PSW) lymph node involvement in rectal cancer is uncertain.

Methods: Magnetic resonance images were reviewed retrospectively by specialist gastrointestinal radiologists for the presence of suspicious PSW nodes. Scans and outcome data were from patients with biopsy-proven rectal cancer and a minimum of 5 years' follow-up in the Magnetic Resonance Imaging and Rectal Cancer European Equivalence Study.

Evaluation of closure versus non-closure of vaginal vault after vaginal hysterectomy.

This randomised prospective study in 53 women having vaginal hysterectomy for benign conditions compared a closed vault technique with an open technique. Twenty-seven had the vault closed (group A) whereas 26 patients had an open vault (group B). The primary outcomes include, vault haematoma (as detected by ultrasound on day 3) and fever.

Evaluation of the upper urinary tract using transureteric ultrasound--a review of the technique and typical imaging appearances.

Ureteric strictures and pelviureteric junction obstruction often present a diagnostic conundrum to radiologists, particularly after the first-line investigations have failed to provide a definitive answer. Transureteric ultrasonography (TUU) is a relatively novel technique performed by the radiologist, which uses a miniature endoluminal ultrasound probe to interrogate the ureteric anatomy and peri-ureteric soft tissues. In this review, we discuss how TUU is performed, and the normal imaging appearances of the ureter and surrounding anatomical structures.

The use of intra-operative endo-anal ultrasound in perianal disease.

Introduction: Endoanal ultrasound (EAUS) has demonstrated high sensitivity and specificity for the structural imaging of anorectal pathology. This study prospectively assessed the impact of intra-operative EAUS on the surgical management of perianal disease.

Methods: EAUS was performed prior to and after examination under anaesthesia (EUA) in a consecutive series of patients with perianal disease.

Use of helical CT in assessment of crossing vessels in pelviureteric junction obstruction.

Aim: The purpose of this study is to confirm the accuracy of non-invasive helical computed tomography (CT) with multiplanar reformatting in the diagnosis of crossing vessels in patients with pelviureteric junction (PUJ) obstruction.

Materials And Methods: Nineteen patients with confirmed PUJ obstruction underwent CT of the renal area with intravenous contrast medium. Patients shown to have crossing vessels had to undergo a pyeloplasty by open surgery or laparoscopy.

Pictorial review: the sonographic diagnosis of pathology in the Achilles tendon.

This pictorial essay details Achilles tendon pathology using real-time sonography. Characteristic diagnostic images for tenosynovitis, acute and chronic tendinitis, peritendinitis, nodular tendinitis and complete and partial tendon ruptures are described. The anatomy of the Achilles tendon in relation to these diagnoses is discussed.

Panoramic sialography: an alternative technique.

Pantomographic sialography, referred to in this paper as panoramic sialography, was performed on 30 out of 51 patients. In 21 patients, it proved to be a good alternative technique to conventional sialography whilst in the other nine patients it was the principal method used to study the salivary glands. The techniques employed in this study for both conventional and panoramic methods are described.
