DNA Damages on Blood Cells After Cardiac Magnetic Resonance Imaging
Introduction: Along with the increased use of cardiac imaging at clinics there is increased attention to the potential risks related to the methods used like magnetic resonance (MR) and it cannot be ruled out that MR can alter DNA structure. The aim of this review is to assess the impact of routine cardiac magnetic resonance (CMR) scanning on DNA damages in human T lymphocytes....
متن کاملEnergy window setting for optimum Tl-201 cardiac imaging [Persian]
Introduction: Poor sensitivity and poor signal to noise ratio because of low injected thallium dose and presence of scattered photons are the main problems in using thallium in scintigraphic imaging of the heart. Scattered photons are the main cause of degrading the contrast and resolution in SPECT imaging that result in error in quantification. Thallium decay is ve...
متن کاملCardiac and Hepatic T2*-Weighted Magnetic Resonance Imaging
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...
متن کاملAccelerating cardiac cine 3D imaging using k-t BLAST.
By exploiting spatiotemporal correlations in cardiac acquisitions using k-t BLAST, gated cine 3D acquisitions of the heart were accelerated by a net factor of 4.3, making single breathhold acquisitions possible. Sparse sampling of k-t space along a sheared grid pattern was implemented into a cine 3D SSFP sequence. The acquisition of low-resolution training data, which was required to resolve al...
متن کاملHighly accelerated k-t SENSE cardiac perfusion imaging
Figure 2. Upper figure: Comparison of perfusion curves from a 10x k-t SENSE reconstruction using the conventional (9 profiles) and the SENSE reconstructed training data (9x2 and 9x3 profiles undersampled by a factor of 2 and 3 respectively) along with the corresponding absolute error. Lower figure: The same comparison, this time using anisotropic diffusion filtering of the SENSE reconstructed t...
