Cell-free collagen type I matrix for repair of cartilage defects—clinical and magnetic resonance imaging results

Background and objective: Musculoskeletal injuries frequently occur in the ankle in both the athletic and general population. Ankle sprains are among the most frequent types of ankle injuries, which are conventionally diagnosed through clinical examinations. However, magnetic resonance imaging can provide a more precise diagnosis, leading to better injury management and prevention of consequent chronic complications. The present study aimed to examine the significance of magnetic resonance imaging in detecting and assessing changes that occur in ligaments and soft tissues in patients with ankle sprains. Methods: In a prospective study, 50 patients with ankle sprain referred to Rizgary and Erbil Teaching hospitals in Erbil city, Iraqi Kurdistan Region, from March 2018 to April 2019, were included in the study. They underwent clinical evaluation and MRI (GE general electric 1.5 Tesla). Two expert radiologists analyzed the magnetic resonance imaging images, and the results were compared. The collected data were analyzed using SPSS version 23 through descriptive statistics. Results: Most patients (64%) belonged to the age groups of 30-49 years old. Most of them (64%) were males. Most events of ankle sprain (66%) were because of sports and accidents. The clinical evaluation proved 82% of the ankle sprains. Regarding the laterality of the lesions, 60% were spotted in the right ankles and 40% in the left. According to magnetic resonance imaging results, both radiologists diagnosed that the ankle sprains included bone lesions, ligament injury, tendon injury, and effusion. There was an agreement of ≥ 96% between the two radiologists in this regard. The two radiologists were not significantly different in terms of diagnosing the ligament side. As reported by the radiologists based on the magnetic resonance imaging images, the anterior, lateral, and medial tendons were normal in most cases. Conclusion: Magnetic resonance imaging is a vitally important tool that can be utilized reliably and accurately to diagnose and evaluate changes in ligaments and soft tissues in patients with ankle sprains.

Triangular Fibrocartilage

The aim of this study was to evaluate the accuracy of magnetic resonance imaging in the detection of triangular fibrocartilage complex injury through a meta-analysis. A comprehensive literature search was conducted before 1 April 2014. All studies comparing magnetic resonance imaging results with arthroscopy or open surgery findings were reviewed, and 25 studies that satisfied the eligibility criteria were included. Data were pooled to yield pooled sensitivity and specificity, which were respectively 0.83 and 0.82. In detection of central and peripheral tears, magnetic resonance imaging had respectively a pooled sensitivity of 0.90 and 0.88 and a pooled specificity of 0.97 and 0.97. Six high-quality studies using Ringler’s recommended magnetic resonance imaging parameters were selected for analysis to determine whether optimal imaging protocols yielded better results. The pooled sensitivity and specificity of these six studies were 0.92 and 0.82, respectively. The overall accuracy of magnetic resonance imaging was acceptable. For peripheral tears, the pooled data showed a relatively high accuracy. Magnetic resonance imaging with appropriate parameters are an ideal method for diagnosing different types of triangular fibrocartilage complex tears. Level of Evidence: Diagnostic Level III

Objective: Surgical procedure and adjuvant treatment of type I endometrial cancer were affected by some variables assessed preoperatively. Diffusion-weighted magnetic resonance imaging (DWI) is a promising modality in evaluating myometrial invasion and cervical involvement, investigating the diagnostic values of DWI in assessing myometrial invasion and cervical involvement. Methods: A cross-sectional study was conducted. This study involved all type I endometrial cancer patients in Dr. Cipto Mangunkusumo Hospital from April 2016 until April 2019. The depth of myometrial invasion and cervical involvement was examined using 1.5-T MR unit. The result was compared to the surgical pathologic findings as the reference standard. Results: 34 types I endometrial cancer patients were enrolled in this study. The sensitivity of DWI in evaluating myometrial invasion and cervical involvement in type I endometrial cancer was 94.12% and 57.14%, while the specificity was 64.71% and 92.59%, respectively. Conclusion: DWI can provide reliable prognostic variable information about the myometrial invasion and cervical involvement in the preoperative preparation of endometrial cancer patients.
