ABSTRACT
Malignancies were examined by MRI to detect the bone marrow changes. They were 44 patients with acute leukaemia, 4 patients with chronic myelogenous leukaemia, 4 patients with Hodgkins lymphoma, 3 patients with non. Hodgkin s lymphomta and 2 patients with polycythaemia vera. MRI proved to be highly sensitive in detection of focal or dtffuse bone marrow changes in 52 patients [Sensitivity: 100%] and to exclude any bone marrow affection in 5 patients [Specificity: 100%]. In spite of its high sensitivity in detection of bone marrow pathology, MRI could not defive a certain disease. In all haematopoietic malignancies, MRI revealed focal or diffuse low signal intensity on T1 -weighted images and high signal intensity on T2-weighted images. MRI-guided bone marrow biopsy was performed in 26 patients. All were successful and augmented the MRI diagnosis of persistence or relapse of the disease [19 patients], bone marrow aplation with fat replacement [4 patients] and secondary post therapy myelofibrosis [3 patients]. MR1 was proved to be very valuable tool in follow up of patients and in detection of the therapy complications. Its use should restrict the need for bone marrow biopsy to one time at the initial diagnosis

This study was carried out on 73 patients with congenital talipes equinovarus attending the Orthopaedic and Paediatric Departments, Mansoura University Hospital. Careful history, clinical and radiological examination and chromosomal study was carried out for every patient in order to detect the aetiology and the genetic pattern of club foot. We concluded that idiopathic club foot is primarily caused by multifactorial inheritance system modified by intrauterine environmental factors and is affected by the genetic pattern
