MRI of the anatomical structures of the knee: the proton density-weighted fast spin-echo sequencevsthe proton density-weighted fast-recovery fast spin-echo sequence

Abstract: The main advantages of the PD-weighted FRFSE sequence are the increase in contrast between fluid and non-fluid tissues and the time saved by using the procedure. However, in the absence of joint effusion, the PD-weighted FRFSE sequence generates a poorer contrast between the cartilage and meniscus, the cruciate ligaments and fat of the intercondylar fossa.

“…A proton density weighted (PDW) contrast MRI sequence was chosen in this study as it is frequently used to assess pathologies of the knee in a clinical setting [ 11 , 21 ]. The PDW contrast provides data in which the ligaments, menisci and cartilage can be simultaneously assessed for diagnosis with a reasonable scanning time.…”

“…In this paper, we propose an automatic segmentation for trabecular and cortical bone of the femur and tibia in a clinically relevant MR sequence, proton density weighted contrast [ 21 ]. We use a local energy-based level set method to obtain a 3D rough segmentation of trabecular bone and correct the image data from the inhomogeneity problem.…”

“…In the TMJ MRI protocol, PD- or T1-WI is mainly used to diagnose disc malposition. 1 2 3 In a normal joint, the disc is sometimes difficult to identify, as it is located between the cortex of the mandibular condyle and articular eminence in PD image. When the disc is displaced, it is completely surrounded by soft tissues only and is rather clearly visible.…”

“…This signal intensity pattern was similar to that described in the limbs of horse (Smith & Wright, 2012), cattle (Raji et al, 2009) and camel (Hagag & Tawfiek, 2018).In this protocol, using the density of hydrogen atoms in each tissue, the desired contrast is created and that is why the bone, which has a lower density of hydrogen atoms compared to joint fluid, is seen hypodense. For this reason, the PD FATSAT protocol is the first choice for examining the limb joints (Tokuda et al, 2012).…”
