A change in diagnosis resulted from PET/CT imaging of patients who were younger than 40 years with an initial diagnosis of stage I-III breast cancer, according to a retrospective analysis.

Accuracy of lung cancer screens in some geographic regions questioned

By

Positron emission tomography and fludeoxyglucose F18 is less accurate in diagnosing lung cancer from benign disease in areas where histoplasmosis or tuberculosis infections are common.

Lung infections may lessen chance of detecting lung cancer

Lung infections may lessen chance of detecting lung cancer

Certain conditions make it harder to reliably detect tumors, and regions with locally-endemic infectious lung diseases pose an added hurdle for lung cancer detection.

Monitoring the response of bone metastases to treatment with MRI and PET

By

The European Journal of Cancer has released a position statement on recent developments in MRI and PET and how these techniques can be used to detect bone metastases.

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).

Research team makes cancer glow to improve surgical outcomes

Research team makes cancer glow to improve surgical outcomes

Surgical resection is the most effective method for a cancer cure; however, the procedure may not remove the entire tumor, leading to local recurrence. Researchers at the University of Pennsylvania have established a new strategy in which near-infrared (NIR) imaging is used to help visualize the entire tumor.

Noninvasive advanced image analysis may improve care for lung cancer patients

By

Lung cancer patients could receive more precise treatment, and their progress could be better tracked by using a new high-tech method of non-invasive medical imaging analysis, according to a new study.

Combination imaging helps breast tumor differentiation

Combination imaging helps breast tumor differentiation

The use of new technique, which includes four approaches, could reduce unnecessary breast biopsies.

Combination imaging can distinguish malignant and benign breast tumors

Combination imaging can distinguish malignant and benign breast tumors

By

Imaging breast tumors using four approaches together can better distinguish between malignant breast tumors and those that are benign, compared with imaging using fewer approaches.

Molecular imaging visualizes novel way to knock down breast cancer

By

A recent innovation in breast cancer biomarkers seeks to visualize the HER3 receptor, which could mean more comprehensive breast cancer imaging and potential treatments.

Presurgical SPECT/CT shows more cancer than current standard

Presurgical SPECT/CT shows more cancer than current standard

By

Startling data from an international multi-center trial provide growing evidence that sentinel node imaging is more effectively accomplished with hybrid functional imaging utilizing SPECT and CT.

Molecular breast imaging protocol unmasks more cancer in advanced cases

By

Patients with advanced breast cancer that may have spread to their lymph nodes could benefit from a more robust dose of a molecular imaging agent when undergoing lymphoscintigraphy.

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.

MRI catches breast cancer early in at-risk survivors of childhood Hodgkin lymphoma

By

The largest clinical study to evaluate breast cancer screening of female survivors of childhood Hodgkin lymphoma, showed that MRI detected invasive breast tumors at very early stages, when cure rates are expected to be excellent.

Breast tomosynthesis after screening mammography reduces need for ultrasound and biopsies

By

Breast tomosynthesis in the diagnostic workup for one- or two-view focal asymmetry detected at screening mammography resulted in less use of ultrasound, fewer biopsies, and higher positive predictive value for cancer.

Study raises doubts on value of additional imaging before colorectal cancer surgery

By

Among patients with a certain type of colorectal cancer with limited spread to the liver, imaging using PET and CT before surgery did not significantly change the surgical treatment of the cancer, compared with CT alone.

CT in the operating room allows more precise removal of small lung cancers

By

A new technique that brings CT imaging into the operating room will allow surgeons to precisely demarcate and remove small sub-centimeter lung nodules, leaving as much healthy tissue as possible.

Imaging offers clearer picture of odds of success for cancer drugs

By

The quest for new cancer treatments could be revolutionized by advances in technology that can visualize living cells and tissues. These techniques will make it easier to identify which are the most promising new drugs to take forward for patient testing.

PET imaging before surgery reduces unnecessary lung surgery by half

By

New quantitative data suggests that 30% of the surgeries performed for non-small cell lung cancer patients in a community-wide clinical study were deemed unnecessary.

Big data identifies triple-negative breast, oropharyngeal, and lung cancers

By

Big data analytics has predicted if a patient is suffering from aggressive triple-negative breast cancer, slower-moving cancers, or noncancerous lesions with 95% accuracy.

Early relapse risk is higher when omitting radiotherapy in PET-negative early Hodgkin lymphoma

By

The risk of early relapse is increased when radiotherapy is omitted in patients with stage I/II Hodgkin lymphoma whose PET scan findings are negative, according to an interim trial analysis.

Nonexpert information for patients increases inappropriate use of high-cost imaging

Nonexpert information for patients increases inappropriate use of high-cost imaging

By

The increasing use of expensive medical imaging procedures in the United States is being driven, in part, by patient decisions made after obtaining information from lay media and nonexperts.

3D mapping biopsy finds 3x more prostate cancer than ultrasound biopsy

By

Three-dimensional biopsies find more prostate cancers, particularly in the anterior regions, than those guided by ultrasound, according to a new clinical study.

New type of whole body scan could improve treatment of bone marrow cancer

By

A new type of magnetic resonance imaging (MRI) scan, known as diffusion-weighted MRI, could improve care for myeloma and reduce reliance on bone marrow biopsies.

Respiratory motion management: Essential to radiotherapy

Respiratory motion management: Essential to radiotherapy

By

Respiratory motion management reduces radiation exposure to nontarget tissues in patients undergoing treatment of cancers in the chest and abdomen.

Screen high-risk populations for lung cancer

By

High-risk adults age 55 to 80 years should receive annual lung cancer screening with low-dose computed tomography.

Molecular imaging tracer improves accuracy of treatment plans for brain metastases

By

Imaging with a molecular imaging tracer can help distinguish radiation-induced lesions from new tumor growth in patients who have been treated with radiation for brain metastases, according to new research.

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.

3-D mammography increases cancer detection and reduces callback rates

By

Compared with traditional mammography, 3D mammography—known as digital breast tomosynthesis—found 22% more breast cancers and led to fewer callbacks in a large screening study, as researchers reported at the annual meeting of the Radiological Society of North America.
