  Purpose

This study will look at how tumors in the chest and abdomen move when you breathe. Your doctors are studying if extra 4D CT scans and instructions on how to breathe can help predict this type of movement and improve the accuracy of radiation treatment. 4D CT scans are approved by the FDA. A 4D CT scan is different from a regular CT because it moves slower and takes more pictures. It takes pictures of the way your body moves when you breathe. This gives doctors more pictures of your body so that they can match your pictures to the way you breathe.

In this study, instructions on how to breathe will be visual and audio. Visual instructions will be given to you on a computer screen. You will hear audio instructions through a speaker.

Study Population

Patients with Abdominal & Thoracic malignancies who consent to recieving Radiation treatment at the University of Maryland, Baltimore, will be offered this protocol design.

Criteria

Inclusion Criteria:

  • Patients 18 years old or older
  • Patients undergoing a scan in the Department of Radiation Oncology for a thoracic or abdominal lesion(s) and identified as candidates for 4D CT.

Exclusion Criteria:

  • Pregnant or breast-feeding women are excluded.
  • Negative serum or urine pregnancy test prior to study entry is required. Once on the protocol, the patient will be advised and expected to implement an accepted and effective method of contraception such as oral contraceptives ('the pill'),intrauterine devices (IUD's), contraceptive implants under skin or contraceptive injections and condoms with foam.
  • Patients who have difficulty lying flat on their back for extended periods of time will be excluded.
