Women aren't told about postmastectomy radiation therapy, study shows
A population-based study of women living in Detroit and Los Angeles who had mastectomies in 2002 revealed that approximately 19% of them did not receive postmastectomy radiation therapy, even though there were clear indications for its use.

Radiosurgery advised for postpneumonectomy recurrent lung cancer
A large study of patients who developed contralateral lung cancer after having a pneumonectomy suggests that stereotactic radiation therapy is a curative option with minimal toxicity, even for high-risk patients with chronic obstructive pulmonary disease.

Low-dose IFRT works for non-Hodgkin's lymphoma patients
In Europe, low-dose involved-field radiotherapy (IFRT) has been used for years as a palliative treatment for patients with non-Hodgkin's lymphoma due to a high patient response rate and minimal toxicity. Now, researchers in the U.S. are reporting similar findings.

Image Gently organizers look ahead on 1-year anniversary: Part 1
One year ago, a group of radiology and pediatric organizations launched the Image Gently campaign to raise awareness about pediatric radiation dose during CT scans. Twelve months later, the Alliance for Radiation Safety in Pediatric Imaging has succeeded in taking its message to North American radiologists and is now looking to expand its focus, both internationally and to parents and pediatricians.

Experts debate merits of breast reconstruction before radiation therapy
Breast reconstruction is a subject of anxiety and concern for women who face the loss of a breast. The problem is even more pronounced for women receiving radiation therapy as part of their treatment, as experts disagree on whether radiation should be delivered before or after reconstructive surgery.

Virtual bronchoscopy helps find foreign body aspiration in kids
A percentage of children suspected of ingesting a foreign object may be able to avoid conventional bronchoscopy if virtual bronchoscopy is first performed, according to a study published in Emergency Radiology by Turkish researchers.

CT protocol ordering software increases efficiency
At M. D. Anderson Cancer Center, where radiologic technologists perform an average of 700 body and chest CTs each day, the hospital's radiology department saw a major improvement in efficiency when it adopted a CT protocol ordering system to replace manual order forms sent by fax and courier.

Active thyroid surveillance effective, beneficial for older patients
A 58-year-old woman was diagnosed with ER-positive (Allred score 8) ILC in her right breast. Ultrasound and MRI found prominent lymph nodes in right axillary level I area, diagnosed as metastasis on ultrasound-guided fine-needle aspiration. F-18 FES-PET/CT showed a positive mass in right breast (white arrow; SUVmax, 5.6) and multiple F-18 FES–positive lymph nodes in right axillary level I, II, and II/III junction areas (red arrows; SUVmax, up to 12.2). In addition, a small F-18 FES-positive lymph node was observed in the right second internal mammary area (red circles; SUVmax, 1.8). However, biopsy could not be performed because it was too small and not visible on ultrasound; the clinician decided to include internal mammary lymph node in treatment field for adjuvant radiotherapy. The patient underwent lumpectomy with ALN dissection, with five metastases being identified in 13 lymph nodes dissected, and is scheduled to receive adjuvant chemotherapy, radiotherapy, and endocrine therapy.

MRI model predicts treatment response in breast cancer patients
By Amerigo Allegretto
Radiomics scoring derived from contrast-enhanced MRI can predict treatment response in women being treated for triple-negative breast cancer.
September 3, 2024
Axial dynamic contrast-enhanced MRI scans show results from two women before they underwent neoadjuvant chemoimmunotherapy for triple-negative breast cancer. (A) T1-enhanced MRI scan, (B) rate constant for contrast agent plasma-to-interstitial transfer (Ktrans) map, and (C) maximum contrast agent uptake rate (Slopemax) map in a 56-year-old woman depict a tumor that manifested as a spherical 4-cm mass enhancement (arrow in A) in the right breast with axillary node involvement (arrowhead in A). The radiomics score was high, at 3.3. Histopathologic examination after chemotherapy revealed no invasive residual cancer in the breast or the lymph nodes (pathologic complete response). (D) T1-enhanced MRI scan, (E) Ktrans map, and (F) Slopemax map in a 49-year-old woman show a tumor that manifested as a spiculated 3-cm mass enhancement (arrow in D) in the left breast with thickening of the skin (arrowhead in D). The parametric maps show much greater spatial heterogeneity than in the case shown in B and C, with areas of high intensity. The radiomics score was low, at −1.6. Histopathologic examination after chemotherapy revealed a 10-mm invasive residual cancer in the breast (not pathologic complete response). Image courtesy of the RSNA.
