PURPOSE: To determine the accuracy and repeatability of ultrasonography (US) with ellipsoid formula in calculating renal volume. MATERIALS AND METHODS: The volumes 20 volunteers aged 19–51 years were determined by using US magnetic resonance (MR) imaging voxel-count method two independent observers for each modality. performed all measurements twice, an interval between first second examinations. was reference standard. Repeatability evaluated SD difference (method Bland Altman). RESULTS:...

To determine the accuracy of gadolinium-enhanced breath-hold magnetic resonance (MR) angiography in diagnosis renal artery stenosis and visualization accessory arteries.Forty-four patients suspected having 10 potential kidney donors, all whom were scheduled to undergo elective intraarterial digital subtraction (DSA), studied. Three-dimensional gradient-echo MR was performed at 1.5 T with following parameters: repetition time, 13.5 msec; echo 3.5 flip angle, 60 degrees; 195 x 512 matrix;...

Abstract Many sources indicate that smallholder tree-crop commodity farmers are poor, but there is a paucity of data on how many them poor and the depth poverty. The living income concept establishes net annual required for household in place to afford decent standard living. Based datasets cocoa tea Ghana, Ivory Coast Kenya literature, we conclude large proportion such do not have potential earn based their current situation. Because these typically cultivate small farm sizes low capacity...

SUMMARY Suppositories containing 300 mg 5‐aminosalicylic acid (1.96 mmol) or 425 acety1‐5‐aminosalicylic were used in 40 patients with idiopathic proctitis to determine the efficacy of acetyl‐5‐aminosalicylic treating this bowel inflammation. Each patient was treated suppositories twice daily for 4 weeks a double‐blind trial. Four included The second time they alternative regimen. Six acetyl‐5‐aminoscylic group did not complete trial, four them because diarrhoea. Complete clinical remission...

Formula scoring (FS) is the use of a don't know option (DKO) with subtraction points for wrong answers. Its effect on construct validity and reliability progress test scores, subject discussion. Choosing DKO may not only be affected by knowledge level, but also risk taking tendency, thus introduce construct-irrelevant variance into measurement. On other hand, FS result in more reliable scores. To evaluate impact radiology residents was divided two tests 100 parallel items (A B). Each had...

The use of cardiac magnetic resonance (CMR) analysis has increased in patients with hypertrophic cardiomyopathy (HCM). Quantification left ventricular (LV) measures will be affected by the inclusion or exclusion papillary muscles as part LV mass, but magnitude effect and potential consequences are unknown.We performed Cine-CMR (1) clinical HCM (n = 55) (2) subclinical mutation carriers without hypertrophy 14). Absolute relative differences ejection fraction (EF) mass were assessed between...

In this paper, we consider how references to ‘development’ are deployed convince communities lease their land agribusiness investors in Sierra Leone. We argue that promises of development made by companies resonate with the aspirations for already have. The existing ‘imaginaries’ development, actual conditions economic hardship and material relations power bound up who does ‘asking’ mean need little convincing give land. Imaginaries effective not only because themselves, but also these...

A 51-year-old previously healthy woman was referred to our institution with atypical chest pain. Physical examination and laboratory findings were normal. The electrocardiogram demonstrated sinus rhythm of 70 beats/min a right bundle branch block. Routine X-ray showed calcifications projecting on the heart. Transthoracic echocardiography hampered by limited acoustic window. Cardiovascular magnetic resonance revealed well-demarcated mass in ventricle conjunction ventricular free wall...
