Moments in Radiology History: Part 16 -- Early nuclear medicine
After early efforts began to harness the power of x-rays for diagnosis and therapy, some physicians and physicists chose to focus instead on the development of radioactive isotopes. In his latest Moments in Radiology History installment, radiology historian Otha Linton examines the advances that ultimately led to the field of nuclear medicine.

Moments in Radiology History: Part 15 -- Mammography's roots
Today's debate over the value of breast screening is nothing new. In fact, controversy has dogged mammography almost since the technique was invented. In his latest installment of Moments in Radiology History, Otha Linton traces the mammography debate through the career of its earliest proponent, Dr. Robert L. Egan.

Moments in Radiology History: Part 14 -- The board exam evolves
From June 20 to 25, the last candidates for certification in diagnostic radiology were tested live by American Board of Radiology volunteer examiners at the Executive West Hotel in Louisville, KY. Future candidates will see a board exam that differs radically from the one to which radiology has become accustomed.

Moments in Radiology History: Part 12 -- Radioisotopes
In the latest Moments in Radiology History column, historian Otha Linton traces the path of radioisotopes from physicist Antoine Henri Becquerel and the Curies to cyclotrons in California, the first treatments of cancer patients, and World War II and the atomic bomb.

Moments in Radiology History: Part 11 -- The 1st residents
The early years of radiology saw many physicians take up the new discipline with little or no formal training. That soon began to change with the establishment of the first radiology residency program in 1915, which accepted one resident, according to radiology historian Otha Linton.

Moments in Radiology History: Part 10 -- RSNA show's early days
When RSNA held its first meeting in December 1915, the conference attracted 30 of the nascent society's 62 members to a Chicago hotel. Now closing in on its 100-year anniversary, RSNA still meets in Chicago, but it draws 60,000 radiology professionals to what has become the world's largest medical meeting.

Moments in Radiology History: Part 9 -- RSNA centennial
As RSNA plans to convene its 2012 meeting in just a few weeks, plans are already being laid for the 100-year anniversary of the Chicago congress. In his latest column, radiology historian Otha W. Linton describes how the RSNA rose from humble Midwestern roots to become one of the pre-eminent medical societies in the world.

Moments in Radiology History: Part 8 -- Imaging of black lung
In 1969, the U.S. Congress passed a new piece of legislation on coal mining that called for compensation to miners who had developed pneumoconiosis, or black lung. The new program relied heavily on medical imaging to detect the disease, with radiology playing a major role in the program's implementation.

Moments in Radiology History: Part 7 -- Early x-ray treatments
Today, diagnostic radiology and radiation oncology are distinctly separate disciplines -- but things weren't always that way. In fact, the early pioneers of radiology began experimenting with the new rays for therapeutic purposes almost as soon as they were discovered.

Two cases of pathologically confirmed intrahepatic cholangiocarcinomas in 68-year-old male patients. In both cases (A-H, case 1; I-P, case 2), CT scans (B, F, case 1; J, N, case 2) revealed intrahepatic bile duct dilation and suspected nodular lesions. While F-18 FDG PET/CT (A, C, D, case 1; I, K, L, case 2) failed to demonstrate abnormal tracer uptake (SUVmax 3.5, TBR 1.3 in Case 1; SUVmax 2.6, TBR 1.2 in Case 2), F-18 FAPI-04 PET/CT (E, G, H, case 1; M, O, P, case 2 ) showed positive uptake in the nodular lesions (SUVmax 9.7, TBR 3.5 in Case 1; SUVmax 9.6, TBR 3.3 in Case 2).

The number of all visible structures was fewer at an ambient light of 500 lux compared to both 25 and 75 lux. In addition, structure visibility was better with a gray wall color at all ambient light levels. Paired comparison between monitors showed better structure visibility on the high specification monitor for all condition.
