Hemosiderin is also generated from the abnormal metabolic pathway of ferritin. It is only found within cells (as opposed to circulating in blood) and appears to be a complex of ferritin, denatured ferritin and other material. The iron within deposits of hemosiderin is very poorly available to supply iron when needed. Ferritin is water soluble and shortens both, T1 and T2 relaxation, with as result a signal change on the MR images. Hemosiderin, a degradation product of ferritin, is water-insoluble with a Topics are presented under the following headings : (1) Amianthoid Fibers and Giant Collagen Fibrils, (2) Ribosome-Lamella Complex, (3) Globular Filamentous Bodies, and (4) Siderosomes, Hemosiderin vs. Ferritin.

What is the difference between hemosiderin and ferritin? Ferritin is water soluble and shortens both, T1 and T2 relaxation, with as result a signal change on the MR images. Hemosiderin , a degradation product of ferritin , is water-insoluble with a stronger T2 shortening effect than ferritin . CONCLUSION: Hemosiderin showed best image contrast on T2*-weighted GRE images but ferritin showed more prominent image contrast on T2-weighted SE than on T2*-weighted GRE images, which may help to determine an appropriate pulse sequence in neurological diseases associated with excessive ferritin accumulation.

When ferritin does not have access to this key ferroxidase enzyme, the iron does not load properly into ferritin, it gets damaged and takes on the properties of hemosiderin, and when that happens, the access to that iron becomes compromised. Hemosiderin builds up in our tissues and organs as we age.
These samples were chosen because Mossbauer spectroscopic measurements on the samples indicated that they exemplified the variation in magnetic and mineral structure found in mammalian tissue iron oxide deposits. represent hemosiderin, calcification, physiological ferritin, melanoma, air, and some paramagnetic contrast agents.7 In particular, T2*-weighted MRI is regarded as a sensitive method for the detection of hemosiderin deposition.8–11 For example, hemosiderin may be detected as an area of signal loss on T2*-weighted images several years after

Types include: Transfusion hemosiderosis Idiopathic pulmonary hemosiderosis Transfusional diabetes Hemosiderin deposition in the lungs is often seen after diffuse alveolar hemorrhage, which occurs in diseases such as Goodpasture's syndrome, granulomatosis with polyangiitis, and idiopathic pulmonary hemosiderosis. Mitral stenosis can also lead to pulmonary hemosiderosis. Hemosiderin
Ferritin is a blood protein and is the main storage protein for iron, alongside hemosiderin. Ferritin is a good indicator of how much iron is stored within your body.

It consists of conglomerates of clumped ferritin particles, denatured proteins, and lipids. The iron within hemosiderin is insoluble, but is in equilibrium with the soluble ferritin pool. Ferritin is water soluble and shortens both, T1 and T2 relaxation, with as result a signal change on the MR images.
