Retrospective Comparative Study to Assess the Pitfalls of Cartigram and the Complementary Role of FSPD in the Evaluation of Cartilage Lesions of Knee Joint
Oral Presentation at the European Congress of Radiology, Vienna, 2019
To analyze the common pitfalls in T2 cartilage maps of the knee joint. To compare visualization of normal cartilage and chondral pathology on Fat Saturated Proton Density (FSPD) and T2 CartiGram by contrast ratio measurements.
Methods and Materials
The contrast ratio of weight-bearing and non-weight bearing cartilage was calculated on the
The contrast ratio between weight-bearing and non-weight-bearing cartilage was statistically significantly higher (p < .05) on the CartiGram for normal cartilage. For chondral pathologies, contrast ratio difference was higher on FSPD
Overlapping of joint capsule tissue with posterior femoral cartilage leads to a spurious assumption of intact femoral cartilage on
