abstract the current mainstay of treatment in spontaneous intracranial hypotension (sih) is an epidural blood patch (ebp). although magnetic resonance imaging (mri) has a well-established role in the diagnosis of sih, imaging features regarding the treatment efficacy of ebp have rarely been discussed. we therefore sought to investigate and compare the sequential brain mri studies before and aft...

in this paper, we propose and investigate distribution of intravascular and extravascular extracellular volume fractions (dieef) as a noninvasive biomarker for neovascularization assessment by dynamic contrast‑enhanced magnetic resonance imaging (dce‑mri). a generalized two‑compartment exchange model (g2cxm) that uniformly includes the patlak model, tofts model, extended tofts model, and recent...

Abstract Background Iron overload is the main transfusion related side effects in patients with transfusion dependent hemoglobinopathies. Severe iron deposition in tissues leads to organ dysfunction. Many organs can be affected such as heart, liver, and endocrine organs. Cardiac failure and liver fibrosis are the consequent of Iron overload in transfusion dependent hemoglobinopathy. Magne...
