MRI helps find contact lens embedded in eye for 28 years
With the help of MRI, ophthalmologists in the U.K. were able to discover what was causing eyelid swelling in a 42-year-old woman: a hard contact lens that had been embedded in her eye for 28 years. The bizarre case was published on August 10 in BMJ Case Reports.

U.K. research could lead to flexible x-ray detectors
What if x-ray detectors were flexible enough to conform to patient anatomy? Would they produce better image quality or enable more accurate monitoring of radiation dose? It may not be a pipe dream. Researchers from the University of Surrey in the U.K. are working on a digital x-ray detector material that could be fabricated into flexible x-ray detectors.

Australian agency orders review of Mo-99 procedures
An Australian government agency has ordered a review of radiation safety procedures at another federal agency in charge of running the nuclear reactor that was forced to stop shipments of the radioisotope molybdenum-99 (Mo-99) last month. The halt has spurred an ongoing shortage of important radiopharmaceuticals in the country.

U.K. reduces tally of women affected by screening blunder
The U.K. breast screening blunder has apparently not affected as many women as initially feared, according to a statement made this week by government officials. The latest estimate is that as many as 75 women may have died as a result of not being screened, compared with an initial estimate of as many as 270.

Why did the U.K. breast screening glitch go undetected?
Could the U.K. National Health Service have detected sooner the fact that nearly 500,000 women were not invited to their final round of mammography in the country's national breast screening program? The authors of a new correspondence article published on 24 May in the Lancet suggest that it might have.

Could legal liability sink breast screening in Ireland?
The prospect of growing legal costs in the Republic of Ireland's national breast screening program could threaten the ongoing viability of the service. The director of the program told news media on 24 May that she has received an increasing number of letters from lawyers representing women whose cancers may have been missed.

Unfilled vacancies and disparities persist in nuclear medicine
Nuclear medicine specialists have high career satisfaction, but unfilled vacancies and career disparities persist, finds a workforce survey by the European Association of Nuclear Medicine (EANM).
Dual PET imaging in Case Two illustrates a patient with discordant disease. FDG PET (b & d) shows FDG uptake in tail of pancreas primary lesion (yellow arrow), as well as multiple hepatic metastases (yellow boxes), with enlarged liver span. DOTATATE PET on left (a) shows several hepatic metastases that do not demonstrate DOTATATE uptake above background of liver parenchyma. The liver lesions in (c) demonstrate moderate FDG uptake in liver lesions, with no corresponding DOTATATE avidity (white box) or central photopenia (white arrow). This discordance in dual PET imaging corresponds to a NETPET score of 5. This suggests de-differentiated disease and a less favorable prognosis. The patient was not suitable for Lutate treatment and received chemotherapy.

Postoperative 3D volume rendering of the fenestrated endograft reconstruction: 3D volume-rendered reconstruction obtained in Horos using the standard soft-tissue preset. The image displays the postoperative appearance of the fenestrated endograft and visceral stents, extending from the descending thoracic aorta to the iliac bifurcation, acquired during the follow-up CT angiogram one month after the procedure. The reconstruction shows patent visceral branches with well-perfused stents, absence of endoleak, and successful restoration of the previously disconnected left limb with adequate iliac perfusion.
