Three-dimensional conformal radiation therapy, or 3D-CRT, involves creating 3-D computer images and delivering highly focused radiation to tumors while sparing nearby healthy tissue.
Written by Karen Selby, RN | Medically Reviewed By Dr. William Breen | Edited By Walter Pacheco | Last Update: June 4, 2024
3D-CRT is a type of external beam radiation therapy (EBRT), which is the most common radiation treatment used for mesothelioma.
New methods of providing radiotherapy make irradiating the affected area more precise. Conforming the radiation beam to the three-dimensional shape of the tumor reduces the risk of side effects.
A treatment session of 3D-CRT typically lasts 15 to 30 minutes, although the first appointment may be longer.
Intensity-modulated radiation therapy (IMRT) is an advanced form of 3D-CRT. It is even safer and more effective for pleural mesothelioma.
IMRT uses the precise 3D targeting of 3D-CRT but also changes the speed and strength of the radiation beams in certain areas.
In 2021, mesothelioma researchers published their findings on 3D-CRT in the Journal of Thoracic Disease. They said it can help deliver precise radiation dosages. In palliative care, 3D-CRT can help reduce symptom severity.
Two-dimensional images gathered from a patient’s CT scans, MRIs and PET scans are fed into a dome-shaped projector that rotates. This dome, which is plugged into a computer, projects the images as three-dimensional holograms.
These are not pictorial images like the ones seen on other types of tests. Holograms are light images that show characteristics such as the size, shape and location of the tumor and the organs that surround it.

A part of that ongoing investigation is experimentation with how to deliver high doses of radiation to the chest without damaging normal tissue — especially within the lung.
Research shows that after an extrapleural pneumonectomy (a surgery to remove a lung), it is possible to use 3D-CRT to deliver high doses of radiation without serious risk.
However, the radiation oncologist must be careful about exposing the remaining lung to radiation.
Side effects of 3D-CRT are generally related to the area of the body being treated.
These side effects are usually not serious and go away within four to six weeks after treatment ends. Medication or changes to your diet can help control potential side effects.
Some patients treated with 3D-CRT experience no side effects.
Three-dimensional conformal radiotherapy is a complex process that requires an experienced radiation oncologist. Especially when treating pleural mesothelioma patients.
You should consult with your oncology team to determine if 3D-CRT is the best form of radiation or if radiation therapy is needed at all. Every mesothelioma case is unique.
A mesothelioma doctor will create the best treatment plan based on certain factors. These include the location and size of tumors, their stage and your overall health.
