Ultrasound Imaging

An example of cardiac ultrasound longitudinal strain measurements on the Epsilon EchoInsight software. This can be used to assess cardiotoxicity from chemotherapy agents. 

Brazilian researchers found that the higher the lung ultrasound score the greater the risk of ICU admission, intubation and death. Image courtesy of Julio Alencar

Images in 69-year-old man with biopsy-confirmed Gleason score 7 (3+4) prostate cancer. (a) Pretreatment axial T2-weighted fast spin-echo MRI scan (repetition time msec/echo time msec, 3820/97) shows tumor in midline anterior transition zone (arrow). (b) Intraoperative MRI scan shows contoured rectal wall (red line), prostate margin (blue outline), and region of interest (orange outline). Because the urethra was included in planned treatment volume, a suprapubic catheter was placed for continuous bladder drainage during treatment. (c) Intraoperative MRI scan shows focused ultrasound beam path (blue) overlaid on treatment plan. Rectangles illustrate each sonication spot. (d) Thermal map image obtained during treatment with heat deposition color coded in red overlaid on sonication spot. (e) Axial gadopentetate dimeglumine-enhanced MRI scan (230/2.97) obtained immediately after treatment shows devascularized ablated volume (arrows). (f) Corresponding T2-weighted fast spin-echo MRI scan (3820/97) at 5 months after ablation shows complete involution of transition zone. All seven cores from treatment area margins were negative for cancer at biopsy. Image courtesy of the Radiological Society of North America

The Philips AAA Model integrates software and Philips 3-D ultrasound technologies into a single solution to automatically segment and quantify the size of the aneurysm sac for surveillance of known native and post-EVAR treated AAAs.
