A new technique combines imaging and mathematics to identify aggressive forms of ductal carcinoma in situ (DCIS), or stage 0 breast cancer, from nonaggressive varieties.
For nonsolid nodules identified by CT screening for lung cancer, annual screening with low-dose CT can eliminate the need for biopsy or surgery.
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 CancerJuly 14, 2016
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 screening device provides images with 6 times better contrast of breast tumors and approximately half the radiation dose of standard mammography.
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.
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.
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.
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.
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
Similar survival seen for PET-CT-guided surveillance and planned neck dissection, but fewer operations.
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 ModalityMarch 09, 2016
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.
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.
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.
Ultrasound has comparable sensitivity in detecting breast cancer compared with mammography and should be considered when testing for the disease.
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.
A method to better trace changes in cancers and treatment of the prostate and lung without the limitations associated with radiation has been developed.
An FDA-approved, magnetic nanoparticle and MRI identifies tumors most likely to respond to drugs delivered via nanoparticles.
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.
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 CriteriaNovember 13, 2015
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 HistoriesNovember 09, 2015
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.
A new laser-based microscope technology may help surgeons see the difference between tumor tissue and normal brain tissue in real-time.
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 CancerOctober 01, 2015
Researchers identified a potential new way to predict which patients with head and neck cancer will benefit most from chemotherapy.
Low-risk cancers that are asymptomatic and presumably will not cause problems in the future are responsible for the rapid increase in the number of new thyroid cancer diagnoses over the past decade, according to a study.
Researchers have discovered that determining a tumor's medulloblastoma subgroup can be achieved noninvasively, using magnetic resonance spectroscopy (MRS).
Researchers have developed a magnetic resonance imaging (MRI) contrast agent with the capability to pinpoint much smaller aggressive breast cancer tumors and micrometastases.
New molecular tools are emerging to identify lung adenocarcinomas during pulmonary resection. The results of a proof-of-concept study suggest that fluorescent imaging of lung cancer during surgery using targeted molecular agents may soon be a reality.
