Subintimal angioplasty for femoro-popliteal occlusive disease.

There has been a longstanding debate about the roles of surgical bypass graft, percutaneous transluminal angioplasty, subintimal angioplasty, and conservative management for femoro-popliteal occlusive disease. Subintimal angioplasty was first described in 1987 as a method of performing an endovascular arterial bypass. The subintimal space at the start of the occlusion is entered with a catheter and a wire loop is used to cross the occlusion and reenter the vessel lumen distally.

The clinical impact of high resolution computed tomography in patients with respiratory disease.

Objective: High resolution computed tomography is widely used to investigate patients with suspected diffuse lung disease. Numerous studies have assessed the diagnostic performance of this investigation, but the diagnostic and therapeutic impacts have received little attention.

Methods: The diagnostic and therapeutic impacts of high resolution computed tomography in routine clinical practice were evaluated prospectively.

High definition three-dimensional ultrasound to localise the tumour bed: a breast radiotherapy planning study.

Background And Purpose: Complex radiation techniques, such as conformal radiotherapy for partial breast irradiation, require accurate localisation of the tumour bed. This study investigated high definition 3D ultrasound for breast tumour bed localisation. Study aims were: firstly, to determine how easily a tumour cavity could be visualised with 3D ultrasound; secondly, to determine the accuracy of computed tomography (CT) and 3D ultrasound co-registration; thirdly, to compare 3D ultrasound with other methods of localisation.

Testicular calcification and microlithiasis: association with primary intra-testicular malignancy in 3,477 patients.

The prevalence of all forms of scrotal and testicular calcification and their association with testicular tumour in a symptomatic paediatric and adult population was investigated. A retrospective study of all testicular ultrasound examinations performed at a single centre over a 5-year period was undertaken. All studies were performed by experienced operators, recorded in a standard method, using high-frequency linear array transducers (> or =10 MHz).

Is sonographically demonstrated mild distal ureteric dilatation predictive of vesicoureteric reflux as seen on micturating cystourethrography?

Background: In most paediatric units, the micturating cystourethrogram (MCU) is the gold standard in the diagnosis of vesicoureteric reflux (VUR). Because of the well-known difficulties associated with MCUs, there is interest in any imaging finding which may be predictive of the absence of VUR with enough confidence to avoid the necessity for an MCU.

Objective: To evaluate whether incorporation of measurement of the internal diameter of the retrovesical ureter into a routine urinary tract US protocol can provide a useful predictor of VUR.
