Background:Approximately 4% of patients diagnosed with early breast cancer have occult metastases at presentation. Current national and international guidelines lack consensus on whom to image and how.Methods:We assessed practice in baseline radiological staging against local guidelines for asymptomatic newly diagnosed breast cancer patients presenting to(More)
Duplex Doppler ultrasound was used to examine 50 breast lesions in 45 patients. Examination was confined to the region of interest, which in most cases was a palpable lump, and the corresponding area of the contralateral breast as a control. In only one patient was a Doppler signal obtained from a normal breast. Nine of the 50 lesions were believed to(More)
The aim of this study was to see how effective ultrasound-guided needle biopsy was at detecting lymph node involvement in patients with early breast cancer. Patients with newly diagnosed invasive breast cancer underwent axillary ultrasound (US) where lymph node size and morphology were noted. A core biopsy (CB) was undertaken of any node greater than 5 mm(More)
Radiography of the excised surgical specimen following wire guided localisation of impalpable breast lesions is standard surgical practice. The aims of the study were to establish the reliability of the breast specimen radiograph (SR) in determining lesion excision and to determine whether the radiographic margin correlated with the histological margin. The(More)
Interval cancer rates are a major determinant of the success of a screening programme. In the Swedish two county study, on which the United Kingdom programme is based, a 39% reduction in mortality was observed in screened women aged 50-64. Using data from the Swedish study, the relationship between interval cancer incidence and the likely future effect on(More)
PURPOSE Quality assurance of MR-guided vacuum-assisted breast biopsy (VAB). METHOD A consensus was achieved based on the existing literature and experience of an interdisciplinary group comprising European specialists in breast imaging and VAB. RESULTS Full imaging work-up must be completed according to existing standards before an indication for(More)
A case of bilateral iliofemoral vein thrombosis in a young man, secondary to testicular seminoma, is presented. Both the acute and chronic thrombus were detectable on abdominopelvic CT without contrast enhancement, and the mechanisms responsible for the differing appearances of the thrombi are discussed. Detection of thrombi in this way may avoid the(More)
Symptomatic hepatic involvement is a rare complication of hereditary hemorrhagic telangiectasia and most commonly consists of fibrosis or cirrhosis. We describe a 33-year-old woman in whom multiple hepatic arteriovenous malformations led to high output cardiac failure and liver failure due to biliary necrosis with refractory biliary sepsis, requiring(More)
Contrast-enhanced (CE) MRI was used to monitor breast cancer response to neoadjuvant chemotherapy. Patients underwent CE MRI before and after therapy, together with conventional assessment methods (CAM). CE MRI was carried out at 1.5 T in the coronal plain with 3D sequences before and after bolus injection. An expert panel determined chemotherapy response(More)
Sixty-three children and adolescent patients who received 78 consecutive orthotopic liver transplants and had serial duplex ultrasound monitoring were retrospectively reviewed for episodes of occlusion of the hepatic artery or portal vein. There were 13 documented episodes of complete occlusion of the main hepatic artery or a major branch, of which nine(More)
