Popis: Aim of this work: To assess the magnetic resonance imaging (MRI) findings compared to plain X-ray in patients with primary nodal osteoarthritis (OA) of first the carpometacarpal (CMC) joint of the thumb. Patients and methods: This study included 35 Egyptian patients with primary nodal hand OA (HOA) and 15 healthy subjects of matched age. Each subject had plain X-rays graded by Kellgren and Lawrence (K–L) score for HOA. MRI testing of both hands done by using T1/T2 weighted axial and coronal images. Results: The mean age was 57.2 ± 8.3 years (45–72 years) and they were 24 females and 11 males. Disease duration of patients ranged (8 months to 10 years, 2.04 ± 1.06 years). In all HOA patients there were signs of knee OA involvement; synovial thickening in 51.4% of patients, knee effusion in 8.6%, limited knee ROM in 28.6% and night pain in 60%. There was a superiority of the MRI in detecting synovitis (71.4%), flexor tenosynovitis (71.4%), collateral ligament (60%), bone marrow lesion (85.7%) and cysts (57.1%) compared to the X-ray which could not detect them. MRI significantly detected osteophytes (88.6%), joint space narrowing (91.4%), erosions (85.7%) and malalignment (57.1%) compared to X-ray (51.4%, 62.9%, 34.3% and 14.3% respectively) (p
