Contrast-Enhanced Subharmonic Imaging

Abstract:
The use of gas filled microbubbles (1 to 10 mm in diameter) as vascular tracers and contrast agents for ultrasound imaging is well established by now. Such contrast agents are used world wide to improve the diagnostic capabilities of ultrasound imaging especially when employed in combination with novel nonlinear contrast imaging modes such pulse inversion second harmonic and subharmonic imaging (SHI). Our group has investigated the use of SHI in breast imaging and has produced the first ever human SHI images. Fourteen patients with 16 breast lesions, who underwent breast biopsies with histopathological assessment, participated in a pilot study of mammography and contrast US. A Logiq 9 scanner (GE Healthcare, Milwaukee, WI) was modified to perform grayscale SHI (transmitting/receiving at 4.4/2.2 MHz). Of the 16 lesions 4 (25%) were malignant. Mammography had a sensitivity of 100 % and a specificity of 20 %. Baseline grayscale US and PDI both achieved a sensitivity of 50 % and a specificity of 92 %, while contrast-enhanced PDI produced 75 % and 75 %, respectively. SHI had a sensitivity of 75 % and specificity of 83 %. All the ultrasound modes produced higher specificities than mammography (p<0.04). The area under the ROC curve for the detection of breast cancer was highest with SHI (0.78); all though the difference was not statistically significant in this small study population (p>0.20). More recently, the utility of contrast microbubbles for quantitative measurements of perfusion (in ml/min/g) and hydrostatic pressure (in mmHg) have been explored. Flash-replenishment techniques and subharmonic perfusion estimation have been explored by our group and others and excellent correlations have been reported (r>0.9). Changes in ambient pressure affect the reflectivity of ultrasound contrast microbubbles leading to an excellent correlation between subharmonic signals and hydrostatic pressure. We have proposed subharmonic aided pressure estimation (SHAPE; U.S. patent 6,302,845) and provided proof of concept of the feasibility of in vivo SHAPE. The aortas of two dogs were scanned with a SHAPE transducer assembly. Simultaneously, the instantaneous pressures within the aorta were measured using a manometer-tipped catheter. The instantaneous in vivo pressure measurements (from the pressure catheter) and those based on SHAPE were in good accordance over a pressure range of 10 to 60 mmHg with standard errors around 5 mmHg. In conclusion, a new contrast specific imaging technique, SHI, has been investigated for in vivo breast imaging and for quantitative measurements. SHI appear to improve the diagnosis of breast cancer relative to conventional ultrasound and mammography; albeit based on a very limited patient population. Some encouraging results in flow and pressure estimation have been achieved.
Bio:
Flemming Forsberg was born in Copenhagen, Denmark on October 20, 1961. He received an M.Sc. in Electronic Engineering and a Ph.D. in Biomedical Engineering from the Technical University of Denmark, Lyngby, Denmark in 1987 and 1990, respectively. From 1987 to 1990 he worked on Doppler ultrasound signal processing at the Electronics Institute, Technical University of Denmark before becoming a post-doctoral research fellow at King’s College, London, England (1990-91). After a year in private industry, developing an intravascular imaging system, Dr. Forsberg went to the department of Radiology, Thomas Jefferson University, Philadelphia, USA where he is currently a Professor of Radiology. His research focuses on ultrasound contrast agents and elastography. Dr. Forsberg is a member of the IEEE and a fellow of the AIUM as well as the AIMBE. He is a member of the Editorial Boards of Ultrasound in Medicine and Biology and Journal of Ultrasound in Medicine.
