Survivors received all modalities of diagnostic imaging at significantly higher rates than controls.
We determined receipt of 5 modalities of diagnostic imaging and associated radiation dose received by survivors and controls from years 5 15 after diagnosis or matched referent date through administrative data.
The registry systematically records data on sociodemographic status, diagnostic circumstances, modalities of diagnostic assessment, tumour characteristics coded according to the International Classification of Diseases for Oncology WHO (1976), stage of the disease at diagnosis, treatment during the first 6 months after diagnosis, survival status and cause of death.

Helical tomotherapy (HT) is a unique IMRT modality that combines elements of diagnostic radiology and radiation therapy in a single unit.
One article evaluated the accuracy of a combination of diagnostic modalities to detect lesions without specifying individual accuracies per modality and was thus excluded [ 46].
For this reason, a number of diagnostic modalities have been proposed, including laparoscopy, clinical scoring systems, computer programs, ultrasonography, CT scans and MRI [7 9].
However, new cases of sarcoid are increasingly diagnosed in TB endemic areas in recent years due to increased awareness and better availability of diagnostic modalities.
Most studies of diagnostic modalities in the last 15 years have demonstrated not only a range of levels of reader aggressiveness, but also a range of level of reader performance.
