![]() Department of Electronics and Instrumentation, Sri Jayachamarajendra College of Engineering, J.S.S.Title:Visualization of Cartilage from Knee Joint Magnetic Resonance Images and Quantitative Assessment to Study the Effect of Age, Gender and Body Mass Index (BMI) in Progressive Osteoarthritis (OA)Īuthor(s): Mallikarjunaswamy Shivagangadharaiah Matada*, Mallikarjun Sayabanna Holi, Rajesh Raman and Sujana Theja Jayaramu Suvarna Cartilage thickness and volume were quantified using image processing techniques in OA affected knee joints. Methods: Visualization of cartilage helps in the assessment of cartilage degradation in diseased knee joints. Keywords: Knee joint diseases, magnetic resonance imaging, osteoarthritis, 3D visualization, body mass index, osteoarthritis. In this work, cartilage is segmented from knee joint MRI, visualized in 3D using Volume of Interest (VOI) approach. Volume correlates with the progression of the disease and can be used for the evaluation of theĬonclusion: The developed methods can be used as helping tool in the assessment of cartilageĭegradation in OA affected knee joint patients and treatment planning. METHODS: MRI was performed on ten healthy volunteers using a 3-T MRI unit with a 3D dual-echo steady-state gradient-recalled echo sequence. People with age 50 years and above and Body Mass Index (BMI) equal and greater than 25. This study aimed to assess the effects of axial leg traction during knee MRI examination on joint space widening and articular cartilage visualization and evaluate the ideal weight for traction. The cartilage thickness and volume is significantly low for Results: The results show that size and volume of cartilage are found to be significantly low in OAĪs compared to normal knee joints. The differences in thickness and volume of cartilage were observed in cartilage in groupsīased on age, gender and BMI in normal and progressive OA knee joints. Of knee joints which include male (56) and female (54) of normal (22) and different stages of OA Statistical analysis is carried out on processed data set consisting of 110 Cartilage thickness and volume were quantified using image processing techniques in compartment of the tibiofemoral joint (PostView Plane Cut showing the. Methods: Visualization of cartilage helps in the assessment of cartilage degradation in diseased exhibited variation of the contact areas as patellar and tibial cartilage mesh. and is caused by the of abnormal contact between acetabular rim and proximal. In this work, cartilage is segmented from knee joint MRI, visualized in 3D Newer MRI techniques, including 3-T scanners with cartilage-sensitive pulse. Volume rendering and 3D visualization can provide an overview of anatomy and diseaseĬondition of knee joint. There are many challenges in proper visualization and quantification of articular cartilage using (MRI) is the most widely used imaging modality in the treatment of knee joint diseases. Visualization and quantification of cartilage is very much essentialįor the assessment of OA and rehabilitation of the affected people. Background: Osteoarthritis (OA) is a degenerative disease of joint cartilage affecting ![]()
