AuntMinnieTV: Study takes aim at physician self-referral

This week's AuntMinnieTV segment tackles one of the most controversial issues in healthcare -- the use of imaging technology by non-radiologist physicians who conduct scans in their own offices.

There are several criteria that any imaging-based screening test must have in order to get traction in today's cost-conscious healthcare environment: The test should be cheap, reimbursable by Medicare, and clinically necessary for a fairly broad segment of the population. If providers can offer the new test without having to buy new equipment, well, that's just icing on the cake.

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.

FES-PET shows promise staging women with invasive lobular cancer

Invasive lobular cancer is the second most common type of breast cancer and is difficult to detect, but FES-PET could aid in surgical staging.

Hypometabolism detected with F-18 FDG-PET in long-COVID patients: putative astrocyte dysfunction and glutamatergic dysregulation. (A) PET scan of a healthy subject. (B) PET scan of a long COVID patient. Hypometabolic areas are indicated with arrows. (C) A diagram showing a healthy condition in which an astrocyte has a normal capacity to take up glutamate and recycle it to sustain glutamatergic neurotransmission, giving rise to normal glucose utilization and lactate production to ensure adequate neuronal energy supply. (D) A diagram showing a long COVID condition in which an astrocyte has reduced glutamate uptake capacity, leading to reduced glutamate recycling, lower glucose utilization (observed with F-18 FDG-PET as hypometabolism) and lower lactate production, dysregulating glutamatergic neurotransmission, and possibly endangering neuronal survival.

Images show fetal T2-weighted fast-spin-echo 0.55-T MRI scans at various gestational ages. (A) Miduterine coronal anatomic views from eight representative healthy pregnant participants (scans in control group); (B) planned brain views in sagittal, coronal, and axial orientation from eight representative healthy pregnant participants (scans in control participants); and (C) lung views from eight representative healthy pregnant participants (scans in control group). The scans are shown in four gestational age ranges.
