1. Microsimulation models demonstrated limited health benefits of supplemental ultrasonography for women with dense breasts and substantial increases in cost. Evidence Rating Level: 2 (Good) Study Rundown: Increased breast density is a risk factor for breast cancer, but its integration into screening remains challenging. An increasing number of states are enacting...
1. Among men referred for prostate biopsy due to an elevated prostate-specific antigen level or an abnormal digital rectal exam, the use of real-time shear-wave elastography (rtSWE) was associated with a high sensitivity for prostate cancer detection and a low false-negative rate. Evidence Rating Level: 2 (Good)   Study Rundown: Prostate...

Patient Basics: Ultrasound

Originally published by Harvard Health What Is It? Ultrasound scanning, also called sonography, is a technique used to see tissues and organs inside the body. It uses high-frequency sound waves, which cannot be heard by humans, to produce images of structures inside the body. The process is very similar to the way...
1. Among asymptomatic women with dense breasts, the combination of automated breast ultrasound (ABUS) with routine screening mammography increased detection rates for invasive cancer when compared to screening mammography alone. Evidence Rating: 2 (Good) Study Rundown: Dense breast tissue limits the sensitivity of diagnostic and screening mammography in a population of...
1. Ultrasound with a vascular endothelial growth factor receptor type 2 (VEGFR2)-targeted contrast agent allowed for noninvasive detection of pancreatic ductal adenocarcinoma (PDAC) in a transgenic mice model. 2. The degree of enhancement with VEGFR2-targeted contrast was significantly higher in PDAC lesions as compared to normal pancreatic tissue. Evidence Rating Level:...
1. Ultrasound- or computed tomography (CT)-guided ovarian mass biopsy yielded diagnostically sufficient samples with a sensitivity and specificity of 100% and 88%, respectively, for malignancy. 2. During the study period, ovarian biopsy procedures resulted in no complications, including no evidence of biopsy tract tumor seeding in patients with epithelial...
1. Point-of-care (POC) ultrasound was equally effective as CT scan in identifying renal calculi at “high-risk” for complications at 30-days after assessment. 2. POC ultrasound reduced radiation exposure at the time of assessment in the emergency department as compared to CT scan. Evidence Rating Level: 1 (Excellent) Study Rundown:...
1. Among patients with a nondiagnostic fine needle aspiration biopsy (FNAB) of thyroid nodules, the use of an ultrasound-based evaluation tool appropriately stratified patients according to malignancy risk.  2. Results suggest that thyroid nodules with two or more suspicious ultrasound features should undergo repeat FNAB, while those with fewer than...
1. There was no difference in long term mortality amongst patients who underwent either fractional flow reserve (FFR)-guided percutaneous coronary intervention (PCI) or intravascular ultrasonography (IVUS)-guided PCI compared to angiography-guided PCI amongst patients undergoing elective or urgent PCI in the London, UK area.  2. Fewer total stents were implanted in...
Image: PD  1.  This model of simulated health outcomes found that screening for cardiac disease by echocardiography or MRI among childhood cancer survivors may be effective at reducing risk, but the frequency of screening could be reduced from current guidelines in order to increase cost effectiveness.  Study Rundown: Childhood cancer survivors are...
