[¹⁸F]fluorodeoxyglucose positron emission tomography (FDG-PET) imaging has been employed as a non-invasive diagnostic tool for malignant tumors. Total lesion glycolysis (TLG) on FDG-PET is calculated by multiplying the mean standardized uptake value (SUVmean) by the tumor volume. Unlike the maximum standardized uptake value (SUVmax), which represents the point of greatest metabolic activity within tumors, TLG has been suggested to reflect global metabolic activity in whole tumors. ⋯ Our findings suggest that TLG may be more useful than SUVmean and SUVmax for predicting PFS and OS in NSCLC patients receiving chemotherapy. The TLG measurement on FDG-PET imaging could be routinely recommended to advanced NSCLC patients.

To assess the image quality (IQ) of an iterative reconstruction (IR) technique (iDose(4)) from prospective electrocardiography (ECG)-triggered coronary computed tomography angiography (coronary CTA) on a 256-slice multi-detector CT (MDCT) scanner and determine the optimal dose reduction using IR that can provide IQ comparable to filtered back projection (FBP). ⋯ Iterative reconstruction techniques can provide 63% ED reduction in prospectively-triggered coronary CTA using 256-slice MDCT while maintaining excellent image quality.

To evaluate the clinical value of the contrast agent SonoVue in the treatment of uterine fibroids with ultrasound-guided high intensity focused ultrasound (HIFU) therapeutic ablation. ⋯ Based on our results, SonoVue may enhance the outcome of HIFU ablation and can be used to assess the extent of treatment.

We compared cost-effectiveness and potential lifetime benefits of using dual-energy computed tomography (DECT) for myocardial perfusion assessment instead of single photon emission computed tomography (SPECT) for the workup of coronary artery disease (CAD). ⋯ Using DECT as the first-line imaging test for myocardial perfusion for the workup of patients with CAD has the potential to provide gains in QALYs, while lowering costs if compared to routine myocardial perfusion SPECT.

Rectus femoris injuries are extremely common in athletes, particularly in soccer players, rugby player, and sprinters. Magnetic resonance imaging (MRI) plays a key role in diagnosis, prognosis, and rehabilitation of these injuries. The current article discusses current concepts in the diagnosis and treatment of rectus femoris injuries in elite athletes, including a discussion of the less well known myofascial injuries and key prognostic factors as seen at MR imaging.
