As a part of the Musculoskeletal and Quantitative Imaging Research Group (MQIR) at UCSF, the Krug Lab is focusing on MR based assessment of trabecular and cortical bone, bone marrow and muscle fat composition using novel MR chemical-shift based imaging techniques. Our research has a particular focus on orthopedic applications. In particular, we are interested in imaging and analyzing the trabecular and cortical bone structure, quantifying bone water content as well as measuring bone marrow and muscle fat composition using high (3 Tesla) and ultra-high (7 Tesla) magnetic field strengths. To this end, we develop new pulse sequence techniques and advanced digital image processing algorithms. Our clinical focus is to improve early detection and to monitor treatment of related diseases such as osteoporosis, osteoarthritis and bone and bone marrow tumors. Another current focus is the improvement of MR imaging in the presence of metal implants.
Our research effort is currently funded by NIH R01AR057336 (PI: R. Krug).
