Skilled radiologists see abnormalities immediately, and researchers want to learn how they do it.

Higher Radiation Doses May Not Improve Survival in Localized Prostate Cancer

By

New technology has enabled doctors to administer higher doses of radiation to prostate cancer tumors with fewer side effects; however, escalating the dose of radiation may not help patients with localized prostate cancer in the long term.

Breast Cancer Screening Improves Among Low-income Women in Medicaid Expansion States

By

Low-income women in Medicaid expansion states in the United States are more likely to undergo breast cancer screening than those in nonexpansion states, according to a study presented at RSNA 2015.

American College of Radiology (ACR) Releases Updated Appropriateness Criteria, Including 3 New Criteria

By

American College of Radiology updated its Appropriateness Criteria for 19 topics, including 3 new criteria. These guidelines assist clinicians in the most efficacious use of radiology.

3D printing offers innovative method for delivering medication

3D printing offers innovative method for delivering medication

By

The use of 3D printing to construct devices of varied sizes and shapes could become a powerful tool in customizing interventional radiology treatments to individual patient needs.

New imaging system may cut radiation exposure for liver cancer patients

By

An interventional x-ray guidance device approved by the U.S. Food and Drug Administration in 2013 may have the potential to reduce the radiation exposure of patients undergoing intra-arterial therapy for liver cancer.

Technology improves detection and treatment of lung cancer

By

Researchers have developed a technology that improves the detection of tumors during radiation therapy for early stage lung cancer. It uses standard radiography machines and improves their images through a software approach.

Rethinking Breast Cancer Screening: Ultra FAST Breast MRI [EDITORIALS]

Rethinking Breast Cancer Screening: Ultra FAST Breast MRI [EDITORIALS]

Breast cancer screening is once again controversial. In this editorial, the author discusses new research demonstrating the effectiveness of an MRI imaging technique called first postcontrast subtracted T1-weighted image (FAST).

Advanced heart imaging raises lifetime cancer risk of children

By

Children who undergo repeated complex imaging tests that deliver higher doses of radiation may have a slightly increased lifetime risk of cancer, according to new research.

Hyperfractionated radiotherapy improves overall survival in patients with head and neck cancer

Hyperfractionated radiotherapy improves overall survival in patients with head and neck cancer

A multi-institutional, randomized phase III trial of fractionation in locally advanced head and neck cancer demonstrated improved local-regional control and improved overall survival with no increase in late toxicity with hyperfractionated radiation therapy.

Reduced reimbursement for imaging may negatively impact patient outcomes

By

Drastic reimbursement cuts for image-guided breast biopsies, and other medical imaging techniques in the 2014 Medicare Fee Schedule Final Rule, may further reduce women's access to mammography and other breast cancer services.

Screen-film mammography superior to computed radiography for BrCA

Screen-film mammography superior to computed radiography for BrCA

CR systems are 21 percent less effective at detecting breast cancers than screen-film mammography, but digital direct radiography is found to have similar cancer detection rates.

Low-dose CT lung screening has greater sensitivity than radiography

Low-dose CT lung screening has greater sensitivity than radiography

Low-dose computed tomography (CT) lung screening is more sensitive than radiography, and predictors of cancer on low-dose CT have been identified, according to two studies.

Recall rates higher for hospital mammography

By

The rate at which women get called back for additional imaging after screening mammography may be higher at hospitals than at community office practices.

Stereotactic body radiotherapy safe and effective for stage I NSCLC

By

Stereotactic body radiotherapy was found to be safe and effective for stage I non-small cell lung cancer, according to a multi-institutional analysis of patterns-of-care and patterns-of-outcome.

PET and MRI predict effectiveness of chemotherapy in advanced breast cancer

By

For patients with advanced breast cancer, PET and MRI can improve quality of life and survival by providing physicians with information on chemotherapy effectiveness prior to surgery.

Twice as many lung cancers detected by CT as by X-ray at initial screening

By

Centers in the United States can achieve a 20% reduction in lung cancer mortality with low-dose computed tomography (LDCT) versus chest X-ray (CXR) screening that was previously reported by the National Lung Screening Trial (NLST).

Breast cancer detection rates vary by type of digital mammography

By

Digital direct radiography is significantly more effective than computed radiography at detecting breast cancer, according to a new study.

Scatter radiation from mammography does not increase risk of cancer

By

The radiation dose to areas of the body near the breast during mammography is negligible, or very low, and does not result in an increased risk of cancer, according to a new study.

Novel breast screening technology increases diagnostic accuracy

By

Adding three-dimensional imaging to standard digital mammography significantly increases the diagnostic accuracy of radiologists while reducing the rate of false positive recalls.

New treatment on horizon offers hope for metastatic melanoma patients

By

Treatment combining electroporation and the drug DNA IL-12 has yielded preliminary positive results in response to treatment and safety among patients with metastatic melanoma.

Tumor tracking technique may improve outcomes for patients with lung cancer

By

A new tumor-tracking technique delivers higher levels of radiation to moving tumors while sparing healthy tissue in lung cancer patients. This technique is moving closer to the clinic.

20-year study of Chernobyl cleanup workers provides insight on low-dose radiation risks

By

The risk of developing leukemia is significantly increased for the 110,654 workers who helped clean up after the 1986 Chernobyl nuclear power plant accident. The results of this 20-year study may help scientists to better define the cancer risk associated with low doses of radiation from medical diagnostic radiation procedures.

Is amifostine still used as a radioprotectant?

This week, the Advisor Forum answers a question about the use of amifostine (Ethyol, generic) as a radioprotectant.

Digital mammography improves population-based breast cancer screening

By

A switch from screen-film mammography to digital mammography improved the detection of life-threatening cancer without significantly increasing the detection of clinically insignificant disease in a large, population-based breast cancer screening program.

Childhood Radiation Exposure of Pancreas Linked to Diabetes

Childhood Radiation Exposure of Pancreas Linked to Diabetes

Dose-response association seen for radiation to pancreas tail and diabetes risk.

In patients with an ICP/ICD, multidisciplinary approach with frequent assessments heightens safety during radiation

By

An approach focusing on patient education and assessments by a multidisciplinary team improved safety in patients with a pacemaker device.
