“…[23] Some of the features which helped in ultrasonography in determining malignancy are shown in Figure (2) i.e., presence of thick septa, papillary projections, heterogenous echotexture. (24) Benign tumours were characterised by unilocularity, thin septae, isoechogenicity and thin walled capsule.…”

PURPOSETo evaluate the appropriateness of combining colour Doppler with gray scale ultrasonography in suspicious adnexal masses. To evaluate the efficacy of this combination in differentiation of benign and malignant masses compared to 2D Gray Scale Ultrasonography alone. METHODSForty six patients with suspicious adnexal masses were evaluated. Morphological characterisation of the masses was done by Sassone Scoring. Colour Doppler parameters were noted and Caruso scoring done. The results were compared to surgical and histopathological findings. RESULTSUsing Sassone Scoring, overall reliability of differentiating adnexal masses had sensitivity of 85% and specificity of 76%. By using Caruso scoring a sensitivity of 85%, specificity of 90% was obtained. By combining sonomorphological score with Doppler indices, specificity increased to 80.9%, PPV increased from 63% to 70.3%. CONCLUSIONIn evaluation of adnexal masses combining Doppler indices with morphological scores gave higher specificity and positive predictive value.

“…The BP cuff was inflated to a pressure of 200 mm Hg and maintained to occlude arteries in the forearm below the transducer for 180 sec. Each measurement sequence consisted of the baseline value (sequence phase 1), values at 30 and 150 sec during occlusion (phases 2 and 3), a value 5 sec after release (phase 4), and four recovery measurements at 20 sec interva]s (phases 5,6,7,8).…”

This study demonstrates that when vascular resistance is low, peak systolic velocity and peak flow volume increase with increasing blood pressure. We used ischemia with reactive hyperemia to create reproducible low resistance conditions in 32 volunteers. Ischemia resulted in sharp increases in systolic and diastolic velocities, while the difference between these velocities increased minimally. Spontaneous variations in subject's systolic blood pressure were positively correlated with peak sys-R ecent reports have shown excellent results in distinguishing malignant from benign ovarian masses by high Doppler shift frequencies and low Doppler index values (RI, PI).t· 3 In other studies, malignant and benign lesions have shown overlap of these measurements.4. . . ' 5 We speculated that systemic BP might be an uncontrolled variable in study populations, accounting for some of the observed inconsistency. To evaluate the potential effect of BP, we used a low resistance is- We conclude that low resistance flow is blood pressure dependent. Because blood pressure increases with age, tumor velocity and frequency shift thresholds may need blood pressure correction if applied over wide age ranges. The resistive index was independent of blood pressure and thus may be preferable.

Under these conditions, we characterized the relationship between spontaneous variations in systemic BP found among our subjects and the corresponding variations in Doppler sonographic measurements of velocity, flow volume, and Rl. SUBJECTS AND METHODSWe studied 32 volunteers (21 male and 11 female) between the ages of 24 and 53 years. None had a history of heart disease, anemia, or use of vasoactive drugs.The subjects were examined while resting supine. The systemic BP was estimated by auscultation of systolic and diastolic Korotkoff's sounds in the brachial artery below a blood pressure cuff on the right upper arm.For the study of Doppler flow during reactive hyperemia, the BP cuff was placed on "the upper right forearm of the subject. A transverse gray scale sonographic image 10 em above the elbow was used to
