OBJECTIVE: A watch and wait policy for patients with a complete clinical response (cCR) after external beam chemoradiotherapy (EBCRT) for rectal cancer is an attractive option. However, approximately a third of tumours will regrow, which requires surgical salvage for cure. We assessed whether contact x-ray brachytherapy (CXB) can improve organ preservation by avoiding surgery for local regrowth. METHODS: From our institutional database, we identified 200 of 573 patients treated by CXB from 2003 to 2012...

The role of ultrasound in the assessment of the female pelvis whether using transabdominal/ transluminal approach is well established. Little reported about the use of the superficial transperineal approach that could provides full assessment of the lower cervix and vagina which may be overlooked in the standard examinations. Proximity of the probe to the vagina helps not just the detection of organ abnormalities yet also proper characterization and differentiation of vaginal masses. Advances in Knowledge: The indications, technique of scanning and limitations of transperineal ultrasound in the evaluation of the lower uterine segment...

In the majority of patients with raised intracranial pressure, the papilledema is bilateral. Unilateral papilledema is rare in conditions causing intracranial hypertension, and it has been described in Foster-Kennedy syndrome and in some cases of idiopathic intracranial hypertension. It has never been reported in cerebral venous thrombosis. We report a young lady presenting with features of subacute onset of headache with seizures, on evaluation she had superior sagittal and bilateral lateral sinus thrombosis...

BACKGROUND Synchronous bilateral breast cancer is rare. A case is presented where whole breast irradiation (WBI) was planned after breast conserving surgery in a patient with synchronous bilateral breast cancer. A comparison was made between the feasibility of helical tomotherapy and direct tomotherapy. CASE REPORT A 60-year-old woman was found to have bilateral breast nodules on routine mammographic screening, resulting in bilateral lumpectomy and sentinel lymph node biopsy. Histopathology showed a 6 mm diameter invasive ductal carcinoma in the right breast (Grade 1, hormone receptor positive, HER2 negative) and an 8mm diameter tubular carcinoma in the left breast (Grade 1, hormone receptor positive, HER2 negative)...

BACKGROUND: Early detection and interventions have enabled patients with sickle cell disease (SCD) to live well into adulthood. Consequently, the chronicity of SCD allows for the insidious manifestation of multisystem complications, including renal damage. Cystic renal lesions are commonly incidentally discovered on ultrasound and computerised tomography (CT) imaging of the abdomen. Most are benign simple cysts, however, difficulties may be encountered if infection, rupture, haemorrhage or cancerous changes develop...

Background and study aims Linear endoscopic ultrasound (EUS) evaluation of the pancreaticobiliary system usually requires scanning from both the stomach and the duodenum. The feasibility of assessing the complete pancreaticobiliary system from the stomach alone has not been studied. We aimed to conceptualize a system-based approach (the railroad approach) for linear pancreaticobiliary EUS (PB-EUS) and evaluate whether the pancreaticobiliary anatomy could be assessed from the stomach alone. Patients and methods Three maneuvers were conceptualized and evaluated (the alpha maneuver in the stomach, and sigma and xi maneuvers in the duodenum)...

Purpose To investigate whether ultrasound follow-up for the detection of postpartum retained products of conception (RPOC) in women considered at risk for this condition may allow for early diagnosis. Methods Parturients at risk for RPOC underwent an ultrasound exam on the second postpartum day. Based on the ultrasound findings, women were either: (1) discharged to routine postpartum care in cases of normal scans, (2) invited for follow-up in cases of abnormal scans. We retrospectively analyzed the rates of women requiring uterine evacuation due to persistent abnormal scans...

BACKGROUND: Failed back surgery syndrome (FBSS) has a high incidence following spinal surgery, is notoriously refractory to treatment, and results in high health care utilization. Spinal cord stimulation (SCS) is a well-accepted modality for pain relief in this population; however, until recently magnetic resonance imaging (MRI) was prohibited due to risk of heat conduction through the device. OBJECTIVES: We examined trends in imaging use over the past decade in patients with FBSS to determine its impact on health care utilization and implications for patients receiving SCS...

INTRODUCTION: We have developed a new knowledge base intelligent system for obstetrics and gynecology ultrasound imaging, based on an ontology and a reference image collection. This study evaluates the new system to support accurate annotations of ultrasound images. We have used the early ultrasound diagnosis of ectopic pregnancies as a model clinical issue. MATERIAL AND METHODS: The ectopic pregnancy ontology was derived from medical texts (4260 ultrasound reports of ectopic pregnancy from a specialist center in the UK and 2795 Pubmed abstracts indexed with the MeSH term "Pregnancy, Ectopic") and the reference image collection was built on a selection from 106 publications...

PURPOSE: Dynamic contrast-enhanced ultrasound (DCE-US) can be used for calculating organ perfusion. By combining bolus injection with burst replenishment, the actual mean transit time (MTT) can be estimated. Blood volume (BV) can be obtained by scaling the data to a vessel on the imaging plane. The study aim was to test interobserver agreement for repeated recordings using the same ultrasound scanner and agreement between results on two different scanner systems. MATERIALS AND METHODS: Ten patients under evaluation for exocrine pancreatic failure were included...

A 56-year-old man presented with a chest computed tomography (CT) finding of a right upper lobe nodule, which was diagnosed using brush cytology as adenocarcinoma stage IB (cT2aN0M0). Repeat CT scan for preoperative evaluation revealed a small, slightly hypodense spot in the pancreatic body, which was diagnosed as pancreatic metastasis from lung cancer using endoscopic ultrasound-guided fine needle aspiration biopsy (EUS-FNAB). Because of the presence of distant metastasis, surgical resection was deferred and chemotherapy was chosen instead...
