An Arizona woman will always remember the incident that was nearly as frightening as learning that she had cancer. The incident was being left inside a PET/CT scanner after the imaging center was locked up and staff had gone for the day. Elvira Tellez, a 67-year-old bone cancer patient from Tucson, was scheduled to undergo a CT exam for metastatic disease in a PET/CT scanner. On Sept. 19, she arrived at Arizona Oncology, a cancer care medical group with 23 facilities statewide that is affiliated with national healthcare network US Oncology.

A nurse and an imaging technologist prepared her for the exam and placed her inside the scanner at about 4 pm. They turned the lights down and asked her not to move. Time passed. The room darkened further when the sun set at 6:25, but, according to Ms. Tellez, no one came to remove her from the scanner tube.

In an exclusive phone interview conducted in Spanish, Ms. Tellez, who speaks little English, said that she had asked the technologist how long the scan would take. "The technologist said, 'No more than 20 minutes.' But they left me inside for 5 hours," she said.

Ms. Tellez called for help when she felt she had been in the scanner too long. With some difficulty, she crawled out of the machine to find she was locked in the clinic as well. Police arrived after a 911 call from her son. She was taken to a hospital for assessment and soon released. Language difficulties did not factor into the incident, she said. The technologist spoke Spanish, and she had good communications with her personal physicians.

Arizona Oncology published an apology on its website a week after the incident, noting that the staff member involved with the case had also personally apologized to Ms. Tellez.

The statement assured patients that an evaluation was completed within 24 hours of the event. It said that the scan was completed successfully and that Ms. Tellez had not been in danger of radiation overexposure. New procedures have been established, including a complete facility sweep and implementation of checks and balances to be completed before the clinic's daily lockdown.

Patient follow through

Such incidents offer a lesson for anyone who cares for imaging patients, said Cindi Luckett-Gilbert, advocacy chair of the SNM's Technologist Section. Nuclear medicine and radiologic technologists receive quality control and quality assurance education specific to their fields. Regardless of training or specialty, however, they should follow through with their patients from beginning to end.
