DWI-MRI predicts pediatric brain trauma outcomes
Diffusion-weighted MR imaging (DWI-MRI) can detect injury in children presenting with traumatic brain injury, even if other neurological signs appear normal, according to the results of a new study. The research demonstrates that DWI is predictive of long-term outcomes in pediatric patients.

Telerad practice integrates faxed patient records with images
A teleradiology practice has developed a software application that automatically integrates patient and exam information transmitted by fax directly into a folder of DICOM patient images. The software application eliminates the clerical time associated with document scanning of paper-based information and significantly reduces the potential risk of mismatched records.

PACS gateway for outside studies speeds trauma treatment
Dealing with external imaging studies can be a tricky business for PACS administrators. It can take time and resources to reformat and import JPEG or even DICOM images into a local network -- time that many emergency departments don't have.

HF weekly radiation effective for elderly breast cancer patients
Results of a clinical study at the Institut Curie in Paris verify that patients with nonmetastatic breast cancer can achieve the same long-term outcomes with conservative surgery followed by weekly high-frequency (HF) radiotherapy as patients who receive conservative surgery followed by daily radiation therapy.

RT toxicity low for HIV-positive prostate cancer patients
HIV-positive patients are able to tolerate pelvic radiation therapy (RT) treatments for prostate cancer without excessive acute toxicity, according to study results. While preliminary, these findings differ from earlier reports that HIV increases the risk of radiation toxicity in patients being treated for pelvic tumors.

Female Hodgkin's survivors have greater risk of secondary cancer
Pediatric Hodgkin's disease survivors aren't necessarily out of the woods, as they have a seven to 18 times higher risk of being diagnosed with cancer as an adult. In addition, the risk is significantly higher for women than for men, according to new study results.

Swiss pediatric CT survey leads to national dose standards
When a child needs a CT exam of the head, chest, or abdomen in Switzerland, pediatricians and parents can be assured that the radiation dose exposure will be identical regardless of the hospital. The country's success in standardizing pediatric CT dose could provide a model for similar efforts under way in the U.S.

Stereotactic body radiotherapy aids patients with metastatic cancer
When a patient learns that cancer has spread from a primary tumor to other anatomic regions, what else can be done? Metastasis is the leading cause of cancer death -- but metastasis is not always widespread and may lend itself to radiation therapy.

Active thyroid surveillance effective, beneficial for older patients
Active surveillance with ultrasound and pathology is effective for patients with early-stage thyroid cancer, especially older ones.
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.

SPECT/CT visualizes heart’s response to tafamidis

SPECT/CT imaging can show over time how patients taking tafamidis for heart disease respond to the treatment.
August 16, 2024
Sagittal, coronal, and axial fused Tc-99m PYP-SPECT/CT images of a 93-year-old male at baseline and after two years of tafamidis 61 mg daily by mouth therapy. Tc-99m PYP images are shown in color and CT images are shown in grey scale. These images show a reduction in visual grade from an initial grade of 3 (myocardial uptake > rib uptake) to a follow-up grade of 1 (myocardial uptake < rib uptake). Quantitative metrics decreased significantly as well.

Dynamic PET/CT and pathologic images for a 66-year-old male participant. (A) Axial dynamic PET/CT image acquired during intravenous administration of Ga-68 PSMA-11 demonstrates the hypermetabolic primary prostatic tumor. The right-sided portion of the lesion used for volume of interest (VOI) analysis is outlined in pink, reflecting the margins seen on a prior T2-weighted MRI scan. Tumor radiotracer uptake extends across midline into the left anterior apex (*). (B) Axial dynamic PET/CT image acquired during selective right prostatic arterial administration of Ga-68 PSMA-11 demonstrates intense radiotracer uptake in the VOI outlined in pink. There is comparatively minimal uptake in the unperfused left-sided portion of the tumor (*). The arterial sheath and catheters in the right groin are partially visualized (arrow). (C) Photomicrograph (hematoxylin-eosin stain; unmagnified) of the prostatic apex after radical prostatectomy. The midline (dotted line) and dominant tumor margins (solid line) are shown. Small additional areas of carcinoma (■) without T2-weighted MRI correlates were also identified at pathologic examination.
