An aching back again? Well don’t sit up straight! With a new type of magnetic resonance imaging , Scottish and Canadian experts have been able to show that sitting in an upright position locations unnecessary strain on the back. Sitting in this posture for hours at a time can lead to chronic back discomfort say the researchers. Lead author Dr acheter suhagra 100 . Waseem Amir Bashir, of the Division of Diagnostic and Radiology Imaging at the University of Alberta Hospital, Canada says ‘sitting in a sound anatomic position is vital, since the strain put on the backbone and its own associated ligaments as time passes can lead to discomfort, deformity and chronic disease’.

Image quality allows for the detection of elevated polyps, however, not of finer mucosal detail such as for example vascular colitis and anomalies. Patients need to take bowel planning because they would for conventional colonoscopy. The colon is distended with surroundings by rectal CT and catheter imaging undertaken, during a solitary breath hold, in both prone and supine positions; that is to minimise false negative and false positive results. Sedation is not needed. Sensitivity for detecting large polyps in professional centres is comparable to colonoscopy; the need for this polyp size threshold relates to the increased probability of current or future malignancy significantly. Sensitivity for polyp recognition decreases with reducing polyp size.. An update on virtual colonoscopy Virtual colonoscopy performed with computed tomography is usually a quick non-invasive technique of imaging the huge bowel that should soon be more widely available in Australia.
