A look ‐locker acquisition scheme for quantitative myocardial perfusion imaging with FAIR arterial spin labeling in humans at 3 tesla
ConclusionThis study shows the feasibility of the LL‐FAIR‐ASL method for the quantification of MBF. The statistical measures reported will allow the planning of future clinical research studies involving rest and stress measurements.

The dorsal skinfold chamber: A versatile tool for preclinical research in tissue engineering and regenerative medicine.
Authors: Laschke MW, Menger MD Abstract The dorsal skinfold chamber is a rodent model for non-invasive microcirculatory analyses of striated muscle and skin tissue throughout an observation period of 2-3 weeks. In combination with intravital fluorescence microscopy, this model allows the quantitative assessment of dynamic processes such as inflammation, angiogenesis, vascular remodelling and microcirculation. Accordingly, the dorsal skinfold chamber is increasingly used for preclinical research in tissue engineering and regenerative medicine. This includes studies on biocompatibility, vascularisation and incorporat...

Nuclear medicine techniques in transplantation
ConclusionNuclear medicine techniques are strongly established as valuable clinical tools in a wide variety of indications, before and after organ transplantation. Furthermore,18F-FDG PET/CT in PTLD and radio-isotopic evaluation of the renal function in putative kidney donors are recommended in clinical algorithms proposed in international guidelines.

Simultaneous assessment of cardiac metabolism and perfusion using copolarized 1 ‐13Cpyruvate and 13C‐urea
ConclusionThe new pulse sequence was used to obtain maps of metabolism and perfusion in the rodent heart in a single acquisition. This hyperpolarized 13C imaging test is expected to enable new studies in which the cardiac metabolism/perfusion mismatch can be studied in the acute environment.

Clinical effects of thermotherapy in combination with intracavitary infusion of traditional Chinese medicine in the treatment of malignant pleural effusion.
Authors: Gu Y, Jiang L, Miao JH, Liang TS, Kan QC, Yang DK Abstract Malignant fluid, a commonly seen tumor associated complication, mainly includes peritoneal effusion, malignant pleural effusion and pericardial effusion. It can produce huge negative influence on the quality of life of patients and even lead to death. Treatment of malignant effusion is one of the effective measures for improving life expectancy of patients. To evaluate the effect of thermotherapy in combination with intracavitary infusion of Kangai injection in treating malignant pleural effusion, 195 patients who received treatment from April 2010...

Differential diagnosis between recurrent gliomas and radiation-induced necrosis using multi-modality imaging
Conclusion: Multi-modality imaging could identify more lesions than PWI, FDG PET/CT and MET PET/CT. Combining MR perfusion imaging and PET/CT could be helpful in differentiating recurrent gliomas from radiation-induced necrosis. Research Support:

Data ‐driven mapping of hypoxia‐related tumor heterogeneity using DCE‐MRI and OE‐MRI
ConclusionThe proposed method locates similar regions to the previous published method of binarization of DCE/OE‐MRI enhancement, but renders a finer segmentation of intra‐tumoral oxygenation and perfusion. This could aid in understanding the tumor microenvironment and its heterogeneity.

Fighting vessel dysmorphia to improve glioma chemotherapy
High‐grade gliomas are aggressive and abundantly vascular tumors, and as in most cancer types, blood vessels in advanced lesions are highly abnormal. Poor perfusion and vascular leakage in tumor tissue resulting in hypoxia, necrosis, and high interstitial fluid pressure can hamper the efficient delivery of chemotherapy. Tumor angiogenesis is known to be supported by host leukocytes recruited to the tumor microenvironment, but the mechanisms leading to dysfunctional vascular network formation are incompletely understood. In this issue of EMBO Molecular Medicine, Mathivet et al () present an elegant study, where longitudi...
