While multidetector CT (MDCT) is most commonly performed for assessment of possible coronary artery disease, technologic advances and dose minimization strategies have enabled the technology’s use as a complementary imaging modality to echocardiography and MR imaging for evaluation of noncoronary cardiac structures.
In an article in the April issue of Radiology (RSNA.org/Radiology), Arthur Nasis, M.B.B.S., of the Monash Cardiovascular Research Centre, Victoria, Australia, and colleagues provide an overview of the noncoronary cardiac structures that can be evaluated on standard MDCT studies and outline the established appropriate clinical uses of MDCT in the assessment of structural heart disease, as well as evolving periprocedural clinical applications. Specifically, the authors discuss assessment of:
“MDCT is being increasingly used for preprocedural evaluation of patient suitability for percutaneous procedures such as transcatheter aortic valve replacement and left atrial appendage device occlusion and for assessment of complications from these procedures,” the authors write.
Regardless of the reconstruction technique used, breast cancer can recur at the mastectomy site and may be recognized at an earlier stage by radiologists who are familiar with the spectrum of imaging findings.
According to an article in the March-April issue of RadioGraphics (RSNA.org/RadioGraphics), by Fanny Maud Pinel-Giroux, M.D., of the Centre Hospitalier de l’Université de Montréal, Canada, and colleagues, radiologists must be familiar with the range of normal and abnormal imaging appearances of reconstructed breasts, including features of benign complications as well as those of malignant change. Along with describing breast reconstruction based on the use of prosthetic implants and various kinds of autologous tissue flaps, the authors:
Evidence in the existing literature is insufficient to support routine mammographic screening in women after autologous breast reconstruction, the authors write. “Although our patient sample was too small to allow definitive recommendations regarding the most appropriate method for monitoring breast health in women after mastectomy and breast reconstruction, the results of our retrospective analysis suggest that systematic follow-up with breast MR imaging might benefit women with a high risk for breast cancer recurrence due to factors such as a histologically aggressive primary tumor type or a genetic susceptibility,” they write.
