“…Previous studies have shown that 1.5 T MRI of the ankle has limitations due to the size and complexity of the joint structure along with restricted in-plane spatial resolution and SNR [3][4][5][6][7][8][9]. Improved image quality with increased SNR makes 3.0 T MR a potential tool to diagnose joint pathology that previously was only suspected or missed [15-17, 25, 26].…”

“…Although magnetic resonance (MR) imaging can serve a major role in ankle pathology assessment and treatment planning [3][4][5][6], it is a challenge as this joint shows a high complexity with relatively small structures distributed within a comparably large volume [7][8][9]. In particular the limited delineation of the talocrural articular cartilage with conventional MR has been documented [10].…”

The objective of this study was to optimize ankle joint MR imaging in volunteers at 1.5 Tesla (T) and 3.0 T, and to compare these optimized sequences concerning image quality and performance in assessing cartilage, ligament and tendon pathology in fresh human cadaver specimens. Initially our clinical ankle protocol consisting of T1-weighted (-w), fat-saturated (fs) T2-w, and short tau inversion-recovery fast spinecho (FSE) sequences was optimized at 1.5 T and 3.0 T by two radiologists. For dedicated cartilage imaging, fs-intermediate (IM)-w FSE, fs spoiled gradient echo, and balanced free-precession steady-state sequences were optimized. Using the optimized sequences, thirteen cadaver ankle joints were imaged. Four radiologists independently assessed these images concerning image quality and pathology. All radiologists consistently rated image quality higher at 3.0 T (all sequences p<0.05). For detecting cartilage pathology, diagnostic performance was significantly higher at 3.0 T (ROC-values up to 0.93 vs. 0.77; p<0.05); the fs-IM FSE sequence showed highest values among the different sequences. Average sensitivity for detecting tendon pathology was 63% at 3.0 T vs. 41% at 1.5 T and was significantly higher at 3.0 T for 2 out of 4 radiologists (p<0.05). Compared to 1.5 T, imaging of the ankle joint at 3.0 T significantly improved image quality and diagnostic performance in assessing cartilage pathology.

“…If the tear is complete, the PLT moves forward into the gap, thus preventing reunion of the PBT slips and eventually gaining contact with the fibular bone (Figures 14 and 15). MRI has been reported as 83% sensitive and 75% specific in the detection of a PBT tear, compared with intraoperative findings [13].…”

ABSTRACT. In spite of highly efficient diagnostic modalities at our disposal, pathological conditions of the peroneal tendons still tend to be underdiagnosed as a cause of lateral ankle pain. The purpose of this review is to summarise and illustrate common and less common MRI findings in repetitive or single mechanical lesions of the peroneal region as well as predisposing anatomical variants. Peroneal tendon (PT) pathology is not uncommon, but is infrequently reported in the literature. It is the main differential diagnosis of lateral ankle pain, next to capsular and ligamentous injuries. Given that normal tendons hardly ever get torn as a result of a single trauma, anatomical predisposition plays an important role in the pathogenesis of degenerative tendinosis and subsequent partial or complete tears of the PT. Rather infrequent causes for primary tenosynovitis are inflammatory conditions of the tendon sheath, e.g. rheumatic or infectious diseases [1]. Ruptured tendons typically exhibit pre-existing degenerative changes on biopsy studies [2]. In spite of some limitations, MRI is the current method of choice for imaging tendons and fibrocartilage. The MRI appearance of different types and grades of tendon injuries has been exhaustively described [3]. T 2 weighted images perpendicular to the tendon course are particularly appropriate for visualising tendinosis and partial or complete tendon rupture, as well as inflammatory changes of the tendon sheath (tenosynovitis). We used T 2 * gradient echo (GRE) sequences as well as T 2 fast spin echo (FSE) sequences; the higher sensitivity of the former allowed for detection of degenerative or traumatic lesions of fibrocartilage [4] and crystal or haemosiderin deposits in the tendon sheaths. However, when looking for tendinosis, the magic angle effect (MAE) must be considered as a source of bright signal in healthy tendons. With short echo time sequences, a signal increase in the absence of morphological change is a normal physical phenomenon in tendons oriented at approximately 55 u to the main magnetic field (Figure 1). Because PTs change direction along their course, the MAE cannot be avoided completely by positioning the foot [5]. The change in Bright signal of both the peroneus brevis tendon and the peroneus longus tendon below the lateral malleolus owing to the magic angle effect in a T 1 SE sequence. The foot is positioned at approximately 10 u plantar flexion with the patient supine in a closed MR scanner with cephalocaudad main field direction.Cite this article as: Schubert R.
