BACKGROUND AND PURPOSE Although ultrasonography-guided percutaneous nephrostomy is relatively safe, a number of factors make it challenging for inexperienced operators. A computerized needle navigation technique using tracked ultrasonography snapshots was investigated to determine whether performance of percutaneous nephrostomy by inexperienced users could be improved. METHODS Ten operators p...

AIM To assess the role of breast ultrasonography as a complement to negative mammography in radiologically dense breasts. MATERIAL AND METHODS Out of a total series of 49,044 consecutive mammograms reported as negative in asymptomatic women, 25,665 (52.3%) were coded as dense (BI-RADS D3-4) and ultrasonography was recommended. Due to organizational problems, ultrasonography was performed imme...

Abdominal adhesions at the stage of surgical treatment limit possibility safe manipulation both access and during surgery. The number complications associated with can be reduced by obtaining data on their localization. variety methods for preoperative detection abdominal is very limited. Ultrasonography, magnetic resonance imaging computed tomography are used this purpose. article first part a...

A seven-year-old un-castrated male Shih Tzu dog was presented with signs of in appetence and dysuria for ten days. Abdominal ultrasonography noticed multiple mucosal projections, isoechoic a mildly thickened bladder wall sledge the urinary bladder. Urine analysis revealed pH 8.5, specific gravity 1.050, struvite crystals microbial culture yielded Staphycolocci Pseudomonas. Present communication...

This cross sectional study was carried out in the department of Radiology and Imaging, Dhaka Medical College Hospital from July 2008 to June 2010 to compare the accuracy of transvaginal ultrasonography and transabdominal ultrasonography in the diagnosis of clinically suspected cases of ectopic pregnancy. Initially 60 patients with clinical suspicion of ectopic pregnancy were included in this st...

The aim of our study was to verify the reliability of transvaginal ultrasonography in the pre-operative evaluation of bladder endometriosis. Six patients with suspected bladder endometriosis were studied. At referral to our department all six women underwent magnetic resonance imaging (MRI), transabdominal and transvaginal ultrasonography, cystoscopy and descending urography. Subsequently all t...

OBJECTIVE To evaluate accuracy and cost of non-invasive diagnostic strategies including magnetic resonance imaging, intestinal ultrasonography, ileocolonoscopy and video-capsule endoscopy in suspected Crohn's disease. METHODS A decision-analytic model was used to assess the costs in low (25%), intermediate (50%) or high (75%) pre-test probability of Crohn's disease. Based on the published acc...

Four methods of gall stone diagnosis after an attack of acute pancreatitis are analysed. Of 128 consecutive patients with acute pancreatitis, 99 patients were discharged from hospital without a definite aetiology. These patients had biochemical tests performed on admission and ultrasonography and oral cholecystography performed six weeks later. The sensitivity for ultrasonography was 87% and th...

Background: Deep vein thrombosis (DVT) is one of the main causes of hospital mortality which can easily be prevented. Three para clinical methods are used to confirm the diagnosis of DVT, which include D-dimer test, venous color Doppler ultrasonography and venography. This study has focused on the prevalence of confirmed DVT in lower limbs based on venous color Doppler ultrason...

Objective: Various practical methods have been used for pregnancy diagnosis in sheep. Methods of pregnancy diagnosis depending on visualization of the conceptus or determination of its secretory products in the maternal blood or in the milk are the most accurate and specific methods for pregnancy. In 1980, B-mode ultrasonography was introduced in the veterinary field and used for pregnancy diag...
