X-ray dose delivered during a longitudinal micro-CT study has no adverse effect on cardiac and pulmonary tissue in C57BL/6 mice.

ConclusionThis study demonstrated that a 5 Gy X-ray dose accumulated over 6 weeks during a longitudinal micro-CT study had no significant effects on the pulmonary and myocardial tissue of C57BL/6 mice. As a result, the many advantages of micro-CT imaging, including rapid acquisition of high-resolution, isotropic images in free-breathing mice, can be taken advantage of in longitudinal studies without concern for negative dose-related effects.

ConclusionsOrbital floor reconstruction performed via transmaxillary endoscopy is a safe technique, which allows for detailed visualization of the fracture rim, avoids external scars, and permits an easier reduction of the prolapsed orbital content into the overlying orbital cavity. Virtual planning plays an important role in defining the appropriate geometry of the bone graft and establishing the optimal reconstruction strategy. Our preliminary results indicate that virtual planning and 3D printing should become part of an integrated protocol for the endoscopic treatment of orbital floor fractures.

Abstract Positron emission tomography (PET) and single photon emission computed tomography (SPECT) are powerful molecular imaging methods for examining disease-related factors in the whole body using specific imaging probes. Recently, we tried to develop molecular imaging probes that specifically visualize pathological factors associated with cancers and infectious diseases. Although survivin is highly expressed in several cancers, its expression is undetectable in non-dividing tissues. Thus, we developed several small molecular imaging probes that target survivin. These ligands not only showed high affinity for s...

Authors: Rice PE, Needle AR, Leicht ZS, Zwetsloot KA, McBride JM Abstract The aim of this study was to examine bone, muscle, strength and stretch-shortening cycle (SSC) performance in young and elderly individuals with an ankle model to elucidate potential effects of ageing that have been suggested to influence fall risk. Moderately active young (n=10; age=22.3±1.3 yrs) and elderly (n=8; age=67.5±3.3 yrs) males completed a peripheral quantitative computed tomography scan on the dominant lower leg, maximal voluntary isometric plantarflexions (MVIP) and SSC tasks: a countermovement hop and drop hops fro...

ConclusionDynamic Contact Area Ratio was significantly lower in patients with anterior shoulder instability compared to controls, confirming the hypothesis of the study. The findings of this study indicate that calculating the Dynamic Contact Area Ratio based on CT scan images may help surgeons in diagnosing anterior shoulder instability.Level of evidenceIII.

We present the case of a 69 years-old man, with an insidious and progressive palsy of the III left CN with 6 months of evolution. CT scan revealed a 1,2 cm lesion located at the suprasellar and pre-pontine cistern at the free edge of the tentorium, initially compatible with the diagnosis of a small meningioma. He was submitted to surgery but surprisingly histopathological analysis revealed a cavernous malformation, intrinsic to the nerve.This is the twelfth reported case of an III cranial nerve CM, and the management of this lesions still doesn't have clear and definitive recommendations regarding treatment. In selected ca...

Researchers are using artificial intelligence to measure a common marker of heart disease via lung cancer screenings. The research was presented at the annual meeting of the Radiological Society of North America (RSNA). Low-dose chest CT is approved for lung cancer screening in high-risk people, such as long-time smokers. While these CT scans are intended to diagnose lung cancer, coronary artery calcium, a measure of plaque in the arteries, is also visible on CT. The coronary artery calcium score derived from CT is a well-established measure that helps doctors decide who should get cholesterol-lowering preventive medicatio...
