Flex m coil

The equipment used was a 1.5 T MRI scanner (Philips, Eindhoven, The Netherlands) Flex-M Coil. STIR Coronal, Axial & Sagital view (FOV 130 mm, TR 3500, TE 50, TI 100) Thickness 3 mm. The radiological interpretation was performed by two experienced sports trauma radiologists. We used a standardize and reproducible scoring system. This score system grades the tear (score 1–3) and tendinopathy (score 1–3). The final score goes from 2 to 6. A final score of 2 indicates a tear < 25% of the tendon thickness and complete homogeneous low intensity or mild focal increased tendon signal on MRI, while a final score of 6 indicates severe tendinopathy with a tear > 50% of the tendon thickness and generalized increased signal intensity on MRI [39 (link)].

For magnetic resonance imaging (MRI), brain hemispheres were washed with PBS and placed in a closed vessel containing Fomblin solution (Sigma-Aldrich, St. Louis, MO, USA) to reduce artifacts and mimic in vivo brain surroundings. MR imaging was performed using a 3 Tesla MRI scanner (Achieva, Philips Healthcare, Best, the Netherlands) and a flex-M coil. Sagittal, axial, and coronal T2-weighted MRI sequences were used as well as axial inversion recovery T1-weighted sequences. Acquisition parameters were as follows: sagittal T2: field of view (FOV) 100 mm, slice thickness 1.8 mm, repetition time (RT) 3000 ms, echo time (ET) 90 ms, acquisition time (AT) 120,953 ms, and matrix 288 × 252; axial T2: FOV 120 mm, slice thickness 2 mm, RT 4000 ms, ET 90 ms, AT 120,512 ms, and matrix 300 × 242; coronal T2: FOV 100 mm, slice thickness 1.8 mm, RT 3000 ms, ET 90 ms, AT 121,539 ms, and matrix 312 × 271; and axial inversion recovery: FOV 100 mm, slice thickness 2 mm, RT 7000 ms, ET 15 ms, inversion time 600 ms, AT 122,136 ms, and matrix 200 × 154. Sagittal plane was used to determine cortical folding by calculation of the ratio between surface area and gyration, whereas white matter area in cm² was measured in coronal plane. Syngo.via software (Siemens Healthineers, Erlangen, Germany) was employed for post-acquisition processing.
