    Notes: Summary The assessment of anemia in patients with rheumatoid arthritis may be difficult, especially when iron deficiency and the anemia of chronic disease coexist. The development of a radioimmunoassay for serum ferritin concentration has aided the detection of reduced body iron stores in uncomplicated iron deficiency, but its use is compromised in clinically active rheumatoid arthritis by the tendency of serum ferritin to behave as an acute phase reactant. In this latter role it correlated well with disease activity in the patients we studied. Followed serially, serum ferritin levels fell in patients whose disease activity improved after institution of appropriate therapy. In anemic patients with clinically inactive disease, supplemental iron was associated with a significant rise in hemoglobin when compared to untreated patients. Serum ferritin levels behaved independently of hemoglobin levels. Therefore even in clinically inactive rheumatoid arthritis, serum ferritin does not accurately reflect an iron deficiency.

    Notes: Abstract. Magnetic resonance imaging (MRI) of the breast brings the advantages of high resolution cross-sectional imaging to breast cancer diagnosis, treatment and research: improved cancer detection, staging, selection of therapy, evaluation of therapeutic response in vivo, detection of recurrence, and even the development of new therapies. Until now breast cancer treatment and research has been impeded by the limited means of evaluating the breast cancer in vivo: primarily clinical palpation and mammography of the breast tumor. A review of the initial studies shows that with the use of paramagnetic contrast agents, MRI has a sensitivity of 96 % for detecting breast cancers. MRI detects multicentric disease with a sensitivity of 98 %, superior to any other modality. The ability of MRI to detect recurrent local breast cancer in the conservatively treated breast is nearly 100 %. MRI is capable of monitoring tumor response to chemotherapy and actually guiding therapeutic interventions such as interstitial laser photocoagulation.
