associated with lower mortality, although not statistically significant. Autopsies revealed frequent thromboembolic disease. These data may inform trials to determine optimal AC regimens. To develop a rapid T mapping protocol using optimized spiral acquisition, accelerated reconstruction, and model fitting. A T -prepared stack-of-spiral gradient echo (GRE) pulse sequence was applied. A model-based approach joined with compressed sensing was compared with the two methods applied separately for accelerated reconstruction and T mapping. A 2-parameter-weighted fitting method was compared with 2- or 3-parameter models for accurate T estimation under the influences of noise and B inhomogeneity. Mito-TEMPO in vitro The performance was evaluated using both digital phantoms and healthy volunteers. Mitigating partial voluming with cerebrospinal fluid (CSF) was also tested. Simulations demonstrates that the 2-parameter-weighted fitting approach was robust to a large range of B scales and SNR levels. With an in-plane acceleration factor of 5, the model-based compressed sensing-incorporated method yielded around 8% normalized errors compared to references. The T estimation with and without CSF nulling was consistent with literature values. This work demonstrated the feasibility of a T quantification technique with 3D high-resolution and whole-brain coverage in 2-3min. The proposed iterative reconstruction method, which utilized the model consistency, data consistency and spatial sparsity jointly, provided reasonable T estimation. The technique also allowed mitigation of CSF partial volume effect. This work demonstrated the feasibility of a T2 quantification technique with 3D high-resolution and whole-brain coverage in 2-3 min. The proposed iterative reconstruction method, which utilized the model consistency, data consistency and spatial sparsity jointly, provided reasonable T2 estimation. The technique also allowed mitigation of CSF partial volume effect. To investigate the diagnostic utilities of imaging parameters derived from T1-weighted imaging (T1WI), diffusion-weighted imaging (DWI) and dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) to differentiate bone metastases from prostate cancer and benign red marrow depositions of the pelvic bone. Thirty-six lesions from 36 patients with prostate cancer were analyzed with T1WI, DWI, and DCE-MRI. The lesions were classified in the bone metastases (n=22) and benign red marrow depositions (n=14). Lesion-muscle ratio (LMR), apparent diffusion coefficient (ADC), volume transfer constant (K ), reflux rate (Kep), and volume fraction of the extravascular extracellular matrix (Ve) values were obtained from the lesions. The imaging parameters of the both groups were compared using the Mann-Whitney U test, receiver operating characteristics (ROC) curves were analyzed. For the ROC curves, area under the curves (AUCs) were compared. The ADC, K , K and V values of bone metastases were significantly higher than those of benign red marrow depositions (Mann-Whitney U test, p<0.05). However, there was no significant difference in LMR between the two groups (Mann-Whitney U test, p=0.360). The AUCs of K K ADC, V and LMR were 0.896, 0.844, 0.812, 0.724, and 0.448, respectively. In the pairwise comparison of ROC curves, the AUCs of K and K was significantly higher than LMR. K , K , V , and ADC values can be used as imaging tools to differentiate bone metastases from prostate cancer and benign red marrow depositions of the pelvic bone. Ktrans, Kep, Ve, and ADC values can be used as imaging tools to differentiate bone metastases from prostate cancer and benign red marrow depositions of the pelvic bone.Tanshinone IIA (tan IIA), a key component of Salvia miltiorrhiza Bung
