Vector Flow Imaging Compared with Digital Subtraction Angiography for Stenosis Assessment in the Superficial Femoral Artery – A Study of Vector Concentration, Velocity Ratio and Stenosis Degree Percentage
Kristoffer Lindskov Hansen, Peter Møller Hansen, Caroline Ewertsen, Lars Lönn, Jørgen Arendt Jensen, Michael Bachmann Nielsen
Stenosis of the superficial femoral artery (SFA) induces complex blood flow with increased velocities. Disease assessment is performed with Doppler ultrasound and digital subtraction angiography (DSA). An alternative is the vector flow imaging method based on transverse oscillation (TO), an angle-independent vector velocity technique using ultrasound. TO is a potential diagnostic tool for the assessment of atherosclerosis and peripheral arterial disease.
EFSUMB Recommendations for Gastrointestinal Ultrasound Part 3: Endorectal, Endoanal and Perineal Ultrasound
Dieter Nuernberg, Adrian Săftoiu, Ana Paula Barreiros et al.
This article represents part 3 of the EFSUMB Recommendations and Guidelines for Gastrointestinal Ultrasound (GIUS). It provides an overview of the examination techniques recommended by experts in the field of endorectal/endoanal ultrasound (ERUS/EAUS), as well as perineal ultrasound (PNUS).
Thyroid Lymphoepithelial Cysts Mimicking Calcified or Solid Nodules on Ultrasonography
Yukie Tsutsuura, Mitsuyoshi Hirokawa, Ayana Suzuki, Hisashi Ota, Maki Oshita, Mitsuhiro Fukushima, Kaoru Kobayashi, Akira Miyauchi
Thyroid lymphoepithelial cysts (TLECs) are rare, and detailed ultrasonography (US) findings have not been reported. This study aimed to examine in detail the US findings for 32 TLECs and to clarify the diagnostic problems associated with them.
