By

Using a computer algorithm to scan images of the esophagus for signs of early esophageal cancer is nearly as accurate as top specialists.

Supine Position Better Informs Surgeons About Tumor Size and Location Before Lumpectomy for Breast Cancer

Considerable deformity of the breast and tumor position occur when placing patients in the prone (face down) position to obtain pre-operative MRI of the breast, compared with placing patients in the supine (face up) position.

New Device Improves Breast Imaging With Less Radiation Exposure

New Device Improves Breast Imaging With Less Radiation Exposure

By

Imaging and Fluorescence Technique Guides Surgical Removal of Otherwise Undetectable Ovarian Tumors

By

A newly created tumor-specific fluorescent molecule combined with an imaging system guided surgeons to removing additional tumors not palpable or visible without fluorescence in patients with ovarian cancer.

PET/CT Hybrid Imaging Technique Provides Accurate Guide for Prostate Cancer Biopsy

PET/CT Hybrid Imaging Technique Provides Accurate Guide for Prostate Cancer Biopsy

By

Prostate-specific molecular imaging at initial biopsy and preoperative planning can accurately determine and delineate the extent of prostate cancer. The imaging technique was a type of PET/CT called 68Ga-PSMA PET/CT.

Referrals for Lung Cancer CT Imaging Screening Remain Low Among Family Physicians

By

Most family physicians report discussing low-dose CT imaging with patients at high risk for lung cancer, but referrals for screening remain low, a study published in the journal Cancer has shown.

Altered Metabolism of Four Compounds Drives Glioblastoma Growth

By

The altered metabolism of methionine, tryptophan, kynurenine, and 5-methylthioadenosine can drive the development of glioblastoma. Results also suggest ways to treat the cancer, slow its growth, and precisely elucidate its extent.

Pill Improves Breast Imaging to Light Up Cancer

Pill Improves Breast Imaging to Light Up Cancer

By

Scientists are developing a pill that illuminates only cancerous tumors, improving on current methods that can identify tumors but cannot conclusively determine whether they are cancerous

Image-Guided Surveillance Beneficial for Head and Neck Cancer

Image-Guided Surveillance Beneficial for Head and Neck Cancer

Similar survival seen for PET-CT-guided surveillance and planned neck dissection, but fewer operations.

Imaging Analysis Nearly Matches Genetic Tests in Determining Need for Chemotherapy in Breast Cancer

By

A new analysis method for magnetic resonance imaging (MRI) data appears to reliably determine whether patients would need hormonal treatment only or also need chemotherapy.

Reliance on PET to Detect Lung or Esophageal Cancer Recurrence May Lead to Overuse of the Imaging Modality

By

In posttreatment follow-up of lung and esophageal cancer, PET scans might be overused to detect cancer recurrence. Furthermore, PET scan use to detect recurrence does not increase survival.

Inconclusive: The Pulmonary Nodules You Need to Follow

Inconclusive: The Pulmonary Nodules You Need to Follow

By

A program in a multifacility health care system is designed to enhance early detection of lung cancer through follow-up of nodules seen on thoracic imaging studies.

Early Trial Results Show Novel Injectable Enables Complete Visualization for Resection of Tumors

Early Trial Results Show Novel Injectable Enables Complete Visualization for Resection of Tumors

By

A new injectable agent causes cancer cells in a tumor to fluoresce, potentially enabling surgeons to locate and remove all of a cancerous tumor on the first attempt.

Breast Cancer Detection Rate of Ultrasound and Mammography Are Comparable

By

Ultrasound has comparable sensitivity in detecting breast cancer compared with mammography and should be considered when testing for the disease.

Additional Breast Cancer Tumors Found on MRI After Mammography May Be Larger, More Aggressive

By

Additional breast cancers found with MRI are sometimes larger and potentially more aggressive than those found on mammography, and in some cases, may necessitate a change in treatment plan.

Novel Imaging Agent More Effectively Monitors Impact of Treatment in Lung, Prostate Cancers

Novel Imaging Agent More Effectively Monitors Impact of Treatment in Lung, Prostate Cancers

A method to better trace changes in cancers and treatment of the prostate and lung without the limitations associated with radiation has been developed.

Using MRI to Follow Magnetic Nanoparticles Predicts Effectiveness of Response to Nanotherapeutics

An FDA-approved, magnetic nanoparticle and MRI identifies tumors most likely to respond to drugs delivered via nanoparticles.

Consistency of Lung Nodules Is Predictive of Lung Cancer Risk in Men and Women

Consistency of Lung Nodules Is Predictive of Lung Cancer Risk in Men and Women

By

Women with a certain type of lung nodule visible on lung cancer screening CT scans face a higher risk of lung cancer than men with similar nodules, according to a study presented at RSNA 2015.

Researchers Show That Pigeons Are Adept at Interpreting Radiologic Diagnostic Images

By

With some training and selective food reinforcement, pigeons performed as well as humans in categorizing digitized slides and mammograms showing benign and malignant human breast tissue.

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.

Risks in LDCT Lung Cancer Screenings Need to be Assessed Before Expanding Eligibility to Persons With Lower Smoking Histories

Risks in LDCT Lung Cancer Screenings Need to be Assessed Before Expanding Eligibility to Persons With Lower Smoking Histories

By

The potential risks and harms of LDCT lung cancer screening in current 20- to 29-pack-year smokers needs to be assessed before recommending LDCT for this group.

By

A new laser-based microscope technology may help surgeons see the difference between tumor tissue and normal brain tissue in real-time.

Menopausal Status is a Better Indicator Than Age for Mammography Frequency

By

In a study conducted to inform American Cancer Society (ACS) breast cancer screening guidelines, a screening mammography once every 2 years was found to be safe for postmenopausal women at average risk of breast cancer.

Imaging Method Has Potential to Predict Effectiveness of Induction Chemotherapy in Patients With Head and Neck Cancer

By

Researchers identified a potential new way to predict which patients with head and neck cancer will benefit most from chemotherapy.

Increased detection of low-risk tumors driving up thyroid cancer rates

By
