Article Title: Real-time 3-D ultrafast ultrasound quasi-static elastography in vivo

doi: 10.1109/TMI.2016.2596706

Figure Lengend Snippet: Schema of the 3-D ultrafast quasi-static elastography framework. The 2-D matrix array emitted 100 plane waves at a rate of 100 volumes/sec (A). For each plane wave, RF backscattered echoes were stored in memories and used to calculate 3-D beamformed volumes using a classical delay-and-sum beamforming (B). 100 of 3-D incremental displacement volumes were then calculated using a normalized 1-D cross-correlation algorithm (C). One 3-D cumulative axial displacement volume was thus computed from the summation of the 100 incremental axial displacement volumes (D). Finally, a 3-D axial strain volume was estimated by applying a least-squares estimator and imaged using Amira Software (E).

Article Snippet: The ultrasound quasi-static elastography method presents the advantages to be fast, non-invasive, easy to implement, conceptually very simple and already widely spread in the world of radiology thanks to several commercial implementations (Hitachi, Siemens).

Article Title: Cystic Breast Masses and the ACRIN 6666 Experience

doi: 10.1016/j.rcl.2010.06.007

Figure Lengend Snippet: A 39-year-old woman was followed up for cysts and complicated cysts. On (A) elastography with Hitachi equipment (or also Toshiba), cysts can have a layered and usually trilaminar appearance (arrows), appearing stiffer (blue on these devices) anteriorly and softer (red on these devices) posteriorly. Sometimes there is an apparent fourth layer (open arrow) in the region of posterior enhancement, analogous to the bright area on Siemens and Philips equipment. This is a simple cyst on (B) B-mode ultrasonography image. (Courtesy of Dr Christopher Comstock, Memorial Sloan Kettering Cancer Center, New York, NY.)

Figure Lengend Snippet: A 35-year-old woman presented for evaluation of a palpable abnormality and was noted to have a cyst on (A) and (C) conventional ultrasonography (L17-5 MHz transducer, Philips Ultrasound, Bothell, WA, USA). (B) On EI (elastography imaging) setting 2, a target or bull’s-eye appearance is seen (white arrow) in which the cyst is a void with a central bright area because of the motion of cyst fluid. Also, a bright area is noted just deep to the cyst (red arrow). (D) On EI setting 1, the cyst a black void (arrow) with posterior bright area. (Courtesy of Richard G.

Article Title: Cystic Breast Masses and the ACRIN 6666 Experience

doi: 10.1016/j.rcl.2010.06.007

Figure Lengend Snippet: A 52-year-old woman underwent screening ultrasonography that showed an incidental circumscribed oval mass with uniform low-level echoes on (A) gray-scale image (arrow) compatible with either complicated cyst or solid mass. (B) Elastogram (Antarres, Siemens-Acuson, Mountain View, CA, USA) shows the lesion to have a bull’s-eye appearance, being centrally white and peripherally dark (arrow), that is typical of a cyst (in this case, a complicated cyst with debris). The lesion measured the same diameter on both images (dotted lines). Stiff lesions, including many cancers, tend to appear larger on elastography. (Courtesy of Wendie A.

Figure Lengend Snippet: (A) On conventional gray-scale ultrasonography (L15-4 MHz transducer), a mass (arrow) is noted which appears mostly circumscribed with posterior enhancement and could be mistaken for a complicated cyst. (B) Shear-wave elastography, in which low-frequency shear waves are induced in the tissue, shows the lesion to be hard (as evidenced by the orange and red overlay, arrows) compared with the softer (blue) surrounding tissue, suggesting malignancy. This proved to be a fibroadenoma. (Courtesy of Dr Valerie Juhan, MD, Hospital La Timone, Marseille, France, via Super Sonic Imagine, Aix, Provence, France; with permission.)

Figure Lengend Snippet: A 48-year-old woman with an oval mass on (A) radial (L15-4 MHz transducer) ultrasonography. The margins are mostly circumscribed, and there is a question of a fluid-debris level (arrow), suggesting a complicated cyst.
