In contrast, the BPP is predominantly an assessment of immediate fetal well-being. This test, principally focused on fetal movement, provides a current state of fetal well-being and is predictive of fetal well-being over the next week of gestation. The test also incorporates a longer-term ...
Contrast venography remains the best reference-standard diagnostic test for suspected upper-extremity acute venous thrombosis and may be needed whenever other noninvasive strategies fail to adequately image the upper-extremity veins. Duplex, color flow, and compression ultrasound have also established a ...
Second, for thyroid nodules suspected of malignancy, contrast-enhanced ultrasonography was performed to further evaluate the nature of the nod- ules. For nodules that were benign or highly likely to be benign after contrast-enhanced examination, it was sug- gested that the patients follow up for...
