Most patients prefer cancer screenings—even when the risks top benefits

"Our findings show that people have a strong desire to do something to address the threat of cancer and that they would prefer to receive a screening test that does not save lives rather than not be screened at all," said lead author Laura Scherer, PhD.

Researchers ID new subtype of prostate cancer

Jun 14, 2018 | Oncology Imaging

Researchers from the University of Michigan Rogel Cancer Center have discovered a new subtype of prostate cancer that occurs in about 7 percent of patients.

The mystery of 'chemobrain' and why imaging isn't revealing all the clues

Jun 13, 2018 | Oncology Imaging

Several aspects of cancer-related cognitive impairment are currently unknown, including why it occurs, how long it lasts and what other health problems it causes. But the real mystery lies in the wide-ranging estimates of how many cancer patients “chemobrain” actually impacts, according to a June 13 article in the Los Angeles Times.

Novel radiation therapy method seeks to preserve sexual health

Jun 13, 2018 | Oncology Imaging

A multicenter clinical trial underway at UT Southwestern in Dallas is testing a new technique that would avoid nerve bundles and arteries commonly affected during prostate cancer radiation therapy in hopes of preserving patients’ sexual function.

Non-invasive MRI reveals kidney disease, cognitive impairment correlation in pediatric patients

Jun 12, 2018 | Diagnostic Imaging

Children with chronic kidney disease may have an increased risk of cognitive impairment due to major blood flow changes occurring in the brain, according to research published June 12 in Radiology.

2 studies find edited CRISPR cells may cause cancer

Jun 12, 2018 | Oncology Imaging

Cancer researchers are taking notice of a pair of studies published Monday in Nature Medicine that found editing a cell’s genomes with CRISPR-Cas9 has the potential to seed cancer and may eventually generate the disease, STAT reports.

Oxygen-enhanced MRI may accurately map hypoxia in renal carcinoma patients, determine success of treatment

Jun 11, 2018 | Advanced Visualization

Intrinsic susceptibility biomarkers were found to successfully provide cross validation of the oxygen-enhanced MRI biomarker perfused Oxy-R when mapping tumor hypoxia in renal carcinoma, according to research published in Radiology.

Are CT lung cancer screening trial markers incorrectly predicting mortality rates?

Jun 11, 2018 | Diagnostic Imaging

Though many single-arm studies using "surrogate markers" have predicted CT screening can reduce lung cancer mortality by 80 percent, randomized clinical trials with larger population cohorts have found such screening has reduced mortality by less than 20 percent.

ASCO 2018: PET imaging may top CT in predicting therapy response in melanoma patients

Jun 06, 2018 | Oncology Imaging

PET imaging may better predict long-term benefits and guide discontinuation of therapy compared to standard contrast CT for patients with metastatic melanoma, according to findings presented Monday, June 4, at the 2018 American Society of Clinical Oncology (ASCO) annual meeting in Chicago.

ASCO 2018: Advanced MRI—aided by AI—classifies brain tumors based on mutation status, decreasing diagnostic uncertainty

Jun 06, 2018 | Artificial Intelligence

Research presented at ASCO 2018 found that using contrast perfusion-weighted MRI enhanced by artificial intelligence (AI) and texture analysis can differentiate between brain tumors according to their mutation status.

Medicare patients who receive mammograms more likely to seek other preventative services

Jun 05, 2018 | Women's Imaging

Women who underwent initial mammography screening were more likely to seek out additional preventative measures—despite a positive or negative result—such as Pap smear, bone mass measurement or influenza vaccine services.

Q&A: Breast radiologist supports update to colorectal cancer screening guideline

May 31, 2018 | Oncology Imaging

Health Imaging spoke with Anjali Malik, MD, a breast radiologist from Washington Radiology in the Washington, D.C. metro area about how the ACS's updated colon cancer screening guideline will impact diagnostic imaging and patient care.

Liquid biopsy may alter treatment of metastatic breast cancer

May 30, 2018 | Women's Imaging

A new study has found that a form of liquid biopsy—circulating tumor cells (CTCs)—may be a key technique for creating a staging system to significantly alter the treatment of metastatic breast cancer (MBC).

ACS recommends beginning colorectal cancer screening at age 45

May 30, 2018 | Oncology Imaging

New guidelines from the American Cancer Society suggest beginning colorectal cancer (CRC) screening at age 45, instead of the current recommendation starting at age 50.

PET/MRI body imaging with full head scan identifies severe brain abnormalities

May 29, 2018 | Oncology Imaging

Routine body imaging with FDG PET/MRI technology provides a wealth of diagnostic information for physicians to better manage oncology patients. A study recently published in the American Journal of Roentgenology, however, suggests that not additionally scanning the entire head may lead to missing brain abnormalities.

New online lung cancer screening tool places emphasis on individualized care

May 29, 2018 | Oncology Imaging

A team of researchers has published a free online tool to help clinicians personalize lung cancer screening decisions for patients. The team hopes to enhance patient understanding and attitudes related to cancer risk, while potentially avoiding unnecessary screenings.

Lung cancer targets more US young women than young men

May 25, 2018 | Oncology Imaging

A new study published May 24 in the New England Journal of Medicine found lung cancer mortality rates are much higher for young women than young men in the U.S., with the higher burden confined to whites and Hispanics.

Director of National Cancer Institute discusses future of AI in imaging, cancer care

May 24, 2018 | Oncology Imaging

Officially sworn in this past October as the Director of the National Cancer Institute (NCI), Ned Sharpless, MD, believes that artificial intelligence will probably be in the future of cancer care.

Surveillance intensity doesn’t equate to earlier detection, improved survival in colorectal cancer patients

May 22, 2018 | Oncology Imaging

A recent JAMA study from University of Texas MD Anderson Cancer Center researchers found no correlation between intensity of post-treatment surveillance and detection of recurrence or survival in patients with stage I, II or III colorectal cancer (CRC).

Robot-assisted imaging may hasten treatment for prostate cancer patients

May 22, 2018 | Oncology Imaging

Researchers have successfully used robot-assisted multispectral-fluorescence imaging to distinguish between healthy and diseased lymphatic flow patterns.

Study shows 2017 ACR ultrasound guidelines accurately ID patients for thyroid cancer biopsy

May 18, 2018 | Oncology Imaging
