Is human-AI ‘symbiosis’ the path forward in chest radiography?

Human-AI symbiosis – rather than totally autonomous AI – should be the current goal for AI in chest radiography.

DCE-MRI determines women at high recurrence risk of breast cancer

By Amerigo Allegretto

DCE-MRI can help distinguish women with high recurrence risk of breast cancer from those with low recurrence risk.

January 24, 2024

Examples of quantification of background parenchymal enhancement (BPE) over fibroglandular tissue (FGT) on breast DCE-MRI scans from three patients. Images from left to right are the first postcontrast T1-weighted images, automated segmentation of the right and left breasts (red contours) and semiautomated tumor segmentation (yellow), automated segmentation of FGT (green), and quantification of BPE (purple) over the FGT regions. (A) Images of a 48-year-old woman diagnosed with invasive ductal carcinoma and assigned a low-risk Oncotype DX distant recurrence risk score (score, 13). The BPE measures at 20% cutoff value were ipsilateral absolute BPE within FGT relative to FGT volume (%BPEF/F) of 9.8% and contralateral %BPEF/F of 9.5%. (B) Images of a 60-year-old woman diagnosed with invasive ductal carcinoma and assigned an intermediate-risk Oncotype DX distant recurrence risk score (score, 19). The BPE measures at 20% cutoff value were as follows: ipsilateral %BPEF/F of 13.3% and contralateral %BPEF/F of 14.7%. (C) Images of a 54-year-old woman diagnosed with invasive ductal carcinoma and assigned a high-risk Oncotype DX distant recurrence risk score (score, 30). The BPE measures at 20% cutoff value were as follows: ipsilateral %BPEF/F of 34.1% and contralateral %BPEF/F of 14.5%. Image courtesy of the RSNA.

Elastography tracks stiffness changes in breast implants

By Amerigo Allegretto

Shear-wave elastography could be used as an indicator of breast implant rupture risk.

January 23, 2024

(A) Examples of B-mode images for the measurement of membrane thickness of implants from each of the four types of implants. Images are presented at the same scale. Membrane thicknesses (B) and then shear moduli measured by ARFI method (C) are compared without dissociation as a function of prosthesis age or implantation time. (NS: p-value > 0.05, *: p-value < 0.05, **: p-value < 0.01, ***: p-value < 0.001).

PET/CT improves diagnostic biopsy rates in lung cancer patients

PET/CT imaging can serve as a metabolic guide to increase the accuracy of needle biopsies in patients with suspicious lung nodules.

January 22, 2024

Patient with extensive lung and pleural disease. (2a) The PET/CT was available prior to the biopsy showing heterogeneous F-18 FDG radiotracer uptake and delineating the most accessible area of increased metabolic activity. (2b) The biopsy was targeted to the area of increased activity area and was positive for malignant diagnosis. Image courtesy of the European Journal of Radiology.

PET/CT scans show value in patients with rare type of pancreatitis

F-18 FDG-PET/CT scans may help predict relapses in patients with autoimmune pancreatitis.

January 19, 2024

F-18 FDG-PET/CT images of patients. (A) Image of a 61-year-old male patient with type 1 autoimmune pancreatitis (AIP) demonstrating diffuse enlargement of the pancreas (arrows). The serum IgG4 level was 2,260.0 mg/dL, and the TLG2.5 was 413.8 g/ml×cm3. According to the nomogram, his relapse probability is more than 95%. The patient discontinued steroid use during the maintenance phase, and 7 months later, he relapsed, with imaging showing diffuse re-enlargement of the pancreas. (B) Image of a 60-year-old male patient with type 1 AIP, showing focal enlargement in the head of the pancreas (arrows). The serum IgG4 level was 980 mg/dL, and the TLG2.5 was 92.7.0 g/ml×cm3. According to the nomogram, the patient’s relapse probability is less than 50%. After symptom relief, the patient did not receive maintenance treatment, and has been followed up for 4 years without relapse. Image courtesy of BMC Gastroenterology.

Unlocking the potential of imaging in Alzheimer’s disease care

In the U.S., Alzheimer's disease cases are projected to rise to nearly 13 million, making effective imaging even more crucial for early identification and effective monitoring and treatment of the condition.
