How long does it take to fully recover from radiation therapy?
Most side effects generally go away within a few weeks to 2 months of finishing treatment. But some side effects may continue after treatment is over because it takes time for healthy cells to recover from the effects of radiation therapy. Late side effects can happen months or years after treatment.
Does radiation always shrink tumors?
Radiation therapy is always a balance between destroying the cancer cells and minimizing damage to the normal cells. Radiation doesn't always kill cancer cells or normal cells right away. It might take days or even weeks of treatment for cells to start dying, and they may keep dying off for months after treatment ends.

What is an MRI?
First, it is important for everyone to understand what an MRI is. MRI stands for magnetic resonance imaging. An MRI uses an extremely powerful magnet to produce an image on a computer screen. When your body is exposed to a magnet, the individual molecules that make up your body are going to respond in a certain way. Depending on the molecular structure, these atoms are going to respond differently. The MRI scan is going to capitalize on these differences to produce a detailed image. An MRI is arguably the most detailed imaging scan that can be ordered. In addition to the quality of the image, there are several other benefits that everyone should understand.

What are the advantages of MRI in radiation therapy?
However, magnetic resonance imaging (MRI) provides unique advantages: added contrast information that can improve segmentation of the areas of interest, motion information that can help to better target and deliver radiation therapy, and posttreatment outcome analysis to better understand the biologic effect of radiation. To take advantage of these and other potential advantages of MRI in radiation therapy, radiologists and MRI physicists will need to understand the current radiation therapy workflow and speak the same language as our radiation therapy colleagues. This review article highlights the emerging role of MRI in radiation dose planning and delivery, but more so for MR-only treatment planning and delivery. Some of the areas of interest and challenges in implementing MRI in radiation therapy workflow are also briefly discussed.
Why is MRI used in radiation oncology?
The increased dosimetric conformity of modern treatment techniques, such as IMRT and VMAT, has generated new constraints on the accuracy of target delineation through imaging in RT. In order to deliver highly conformal treatments accurately, a precise definition of tumor and OAR is needed. This is the main reason MRI has seen increased usage in radiation oncology departments. Although in many cases CT still acts as the master reference scan, MRI provides superior soft-tissue contrast compared to CT, as well as a myriad of information on tumor characteristics that aid the delineation of both the tumor and OARs. The flexibility to acquire multiple contrasts has shown advantages for accurate tumor delineation in a large body of literature over the recent years. The American Association of Physicists in Medicine (AAPM) Task Group (TG-101)20on stereotactic body RT states that MRI is a gold-standard for visualization of brain tumors and “is increasingly used in SBRT applications including prostate, spinal tumors, chest, and solid abdominal tumors.” MRI is routinely utilized in a number of malignancies (Table 1) for treatment planning (Figs. 3–4). T2-weighted imaging, for example, is able to distinguish tumor from normal tissue and fat in rectal and esophageal cancer,21whereas T1-weighted imaging provides good tumor contrast in squamous cell carcinoma in head and neck cancer.22Besides native T1and T2contrast, physiological contrasts such as dynamic contrast-enhanced (DCE), blood oxygen level-dependent (BOLD), and diffusion-weighted imaging (DWI) have been shown to have added value in defining tumor boundaries.23–26Physiological information from DCE, DWI, and BOLD imaging (often all referred to as functional imaging in the RT community) has been successfully used to derive tumor probability maps in prostate cancer, a major male cancer in the Western world.27This information was later used in a large Phase 3 trial, called the FLAME trial,28in which a focal micro boost up to 95 Gy in 35 fractions was given to the tumor (ie, GTV), while the prostate gland (ie, CTV) received a standard dose of 77 Gy in 35 fractions.
What is the difference between a CT and MRI?
Gross tumor volume (GTV) for head and neck cancer is delineated on pretreatment (a) MRI image which is registered to corresponding (b) CT dataset. MRI has higher contrast resolution, which enables tumor visualization and accurate GTV delineation, whereas CT images provide electron density information and are used for on-board registration with cone beam CT.

Can CT scans be used with PET?
In current clinical practice, CT data are sometimes augmented with MRI and PET in the treatment of various malignancies. These images from other modalities are fused with CT data to take advantage of the superior soft-tissue contrast or metabolic information provided by these modalities. MRI provides unique and multiple contrast information. Furthermore, MRI contrast (such as T1, T2, and diffusion) could be tailored to highlight a specific organ or tumor. The sections below will briefly highlight the role of MRI in treatment planning and delivery. However, there are a number of challenges for MRI-only radiotherapy planning and delivery, including lack of electron density information and geometric distortion, which will also be addressed in this review.
Is radiation therapy effective for cancer patients?
In this context, radiation therapy (RT) is playing an increasing role as an important modality along with chemotherapy for the management of cancer patients in most disease sites.2–4It is estimate that 60% of cancer patients are treated with radiation in the management of their disease during their life span.5Even though cost effectiveness of radiation therapy is debated due to heavy initial cost of modern machines and use of national resources,6a true analysis provides a different picture, where radiation is cost-effective in the management of cancer patients.7

The median time for a prostate cancer to shrink is about 18 months (some quicker, some slower). For colon cancers, some may grow more quickly and others may grow more slowly and this will affect how they are killed by radiation.
What happens if a cancer cell doesn't divide?
This is a complex question. The first point to be made here is that, with the exception of spermatozoa and lymphocytes (among the two most rapidly dividing cells in the body), cancer cells die what is called a mitotic death. This means that the cell dies when it attempts to divide. So, if a cell does not divide, then it does not die, but just sits there. At the same time, if a cell doesn't divide, it also cannot grow and spread.
