At MD Anderson, we are dedicated to providing the highest level of patient care, not only by being there for a patient’s cancer journey but also by acquiring the best technology and state-of-the-art imaging equipment available. Although closed-bore scanners are the industry standard and wide bore scanners are usually recommended to patients who are overweight or experience claustrophobia, we offer equipment that not only accommodates all patients but provides high-quality imaging to doctors: wide bore MRI scanners.

A review of her medical records indicates that she did have her bladder biopsy which confirmed bladder cancer. She is starting radiation therapy today with Dr. Cook. Her radiation treatments will be 5 days a week for 5 weeks. She reports that her chronic HTN is stable with medication; her opiate induced constipation is stable. She states that her bowel regimen is on hold due to her having diarrhea. She continues to take Eloquis for DVT in left leg. She is followed by Dr. Rosen for oncologist.

Being a nuclear medicine technology means creating images of different area of the patient’s body and preparing radioactive drugs and administer them to patients undergoing the scans. The technologists

Radiation therapy is the ionization of atoms in tissues resulting in formation of highly reactive radicals in a well-defined, restricted volume (1). In other words, ionizing radiations are used to eradicate tumors and at the same time preserve structure and function of normal tissue. A limitation is prevented from being a problem. If bone marrow or neuronal cells are destroyed or injured, they do not regenerate. However, with radiation therapy, these cells are often saved from injury or destruction, unless the tumor is infecting bone marrow or neuronal cells. Today, radiation therapy is the most popular type of cancer therapy in use. It is used to treat one-half to two-thirds of all cancers, which translates to more than ten percent of the population

Certain tumor middles use conformal radiation therapy, in which CPUs help to properly map the place and amount of the growth.

A recently published multicenter RCT designed to address this topic 26, comparing RP vs RT (a combination of external beam RT and brachitherapy) has enrolled only 89 patients over 5 years, with an insufficient statistical power to make any inference on oncological outcomes.

The amount of radiation people are being exposed to is continuously increasing. Medical imaging plays a big role in this increase, mostly being CT scans. This increase is radiation has been a concern to the public because of the risks patients face. It can result in long-term harm, such as increasing their chances of developing cancer. The concern has been more focused on pediatric patients because of their bodies’ greater sensitivity and they would have a longer amount of time they would have to embody any changes. Four societies started the Image Gently campaign to raise awareness of the need to decreases radiation doses when performing medical scans. Image Gently’s goal is to reduce unnecessary exposure to pediatric patients and was considered

Increasing in accumulative radiation doses may lead to initiate or promote carcinogenesis that can cause damages to the patient. Therefore, there is compulsory to reduction of radiation dose by finding the alternative and to upgrading accuracy in imaging strategies (Martin & Semelka, 2007).

It uses a certain advanced technology to plan an exact amount of radiation dose in relation to the size, shape, and location of the tumor. in this case, linear accelerators are used to deliver radiation in a sculpted dose that conform the shape of the tumor, including the complex shapes. Because of its greater degree of accuracy, IMRT may be a treatment option for patients who have reached the maximum allowable dose of conventional radiation therapy and have a recurrent tumor in the treated area. This review focuses more on studies that was performed which include different types of Radiochromic films and RapidArc radiotherapy treatment. We measure the dose of radiation using Radiochromic films such as Gafchromic EBT, EBT2, and EBT3. This device is often used to verify the amount of radiation needed for treatment. The principal factor in making this selection is often the high spatial resolution offered by this

Linear Accelerators (Linacs) are used to deliver X-rays to a patient. They are designed to deliver multiple beams at once. The combined beam needs to focus on tumours and avoid healthy tissue.

In the TARGIT-A trial, 3451 patients aged 45 years or older with early-stage breast cancer were randomized to either receive IORT or EBRT after BCT. In the IORT group, patients received a single dose of TARGIT with Intrabeam after tumor excision or in the immediate post-operative period. If upon final pathology, the patient was found to be of higher risk with unsuspected criteria such as lobular pathology or lymphovascular invasion, then she would also undergo EBRT after receiving IORT at 45-50Gy. IORT is considered individualized risk-adjusted radiotherapy, whereas the EBRT group is considered a one-size-fits-all radiotherapy. In the EBRT group, patients received a standard course of EBRT of 40-50Gy in 15-25 fractions with or without a tumor bed boost of 10-16Gy in 5-8 fractions.4

One reason I selected the Temple University Health System campus in Philadelphia is because of its affiliation with the Fox Chase Cancer Center. Recognized as a comprehensive cancer center, Fox Chase is committed to innovating cancer treatment through its Molecular Therapeutics Program. I am particularly interested in Dr. Jian Q. Yu’s research. His work in diagnostic imaging of various tumors using radiotracers intrigues me because I synthesize similar novel tracers to image colorectal and breast cancer cells using SPECT and PET imaging at Hunter College and Memorial Sloan Kettering Cancer Center (MSKCC). When I think about my future medical career, I imagine one involving specialized patient care, in radiation oncology, and research, in cancer

Mervyn Cohen, the author of the above explosive article, works at Indiana University in the radiology department(Emeritus). In contrast to the above cited works which embraced ALARA and other radiation dose reduction campaigns, Cohen’s goal is to persuade the imaging community that the ALARA concept and the Image Gently initiative have caused more problems than they have resolved. The article is comprised of multiple subtopics in question form with Cohen’s response listed just beneath them. Cohen begins by discrediting the intent of the initiatives by suggesting they were only created as a defensive response to an article written in a widely-publicized newspaper. He continues his plight to persuade the audience by undermining the methods used

The aim was also to determine which technique, namely 3D-CRT plan, an IMRT plan and a VMAT is regarded as the optimal radiation treatment technique for radical prostate cancer with the least radiation dose to the critical organs around the prostate and the highest dose to the target volume. Results of this study confirmed that both IMRT and VMAT treatment techniques are both beneficial in of sparing OAR and delivering the highest prescribed dose to the target volumes. Both these techniques are suitable for prostate cancer treatment. More dose comparisons would make this study more accurate. Based on the data it was clear the 3D-CRT is not an optimal treatment technique compared to IMRT and VMAT. Both the VMAT and IMRT produced clinically adequate treatment plan for prostate cancer. Based on the data in this study, VMAT delivered slightly favourable dosimetric results. However, the difference between IMRT and VMAT was minimal. VMAT produced more conformal dose distributions if compared with IMRT. Manually measuring the V50 with a cursor on the DVH’s and differences in anatomy were some of the limitations involve in this study. Recommendation would be to increase the sample size and to include more dose comparisons. The more comparisons there are the more accurate and viable the results for this research can

In 2007, it is predicted that almost 1.5 million people will be diagnosed with cancer in the United States (Pickle et al., 2007). More than half of these cancer patients will undergo the use of radiation as a means for treating cancer at some point during the course of their disease (Perez and Brady, 1998). Cancer, a disease caused by an uncontrollable growth of abnormal cells, affects millions of people around the world. Radiotherapy is one of the well known various methods used to treat cancer, where high powered rays are aimed directly at the tumor from the outside of the body as external radiation or an instrument is surgically placed inside the body producing a result of internal radiation. Radiation is delivered to the cancerous regions of the body to damage and destroy the cells in that area, terminating the rapid growth and division of the cells. Radiation therapy has been used by medicine as a treatment for cancer from the beginning of the twentieth century, with its earliest beginnings coming from the discovery of x-rays in 1895 by Wilhelm Röntgen. With the advancements in physics and computer programming, radiation had greatly evolved towards the end of the twentieth century and made the radiation treatment more effective. Radiation therapy is a curative treatment approach for cancer because it is successful in killing cancerous tumor cells and stop them from regenerating.
