Article Synopsis
- The study developed and validated a new ultrasound index to diagnose primary medial-type knee osteoarthritis (OA) by measuring total osteophyte height (TOH) and distance between bones (DBB).
- A DBB of 5.6mm or less was found necessary to diagnose primary medial-type knee OA, while severe deformity required a TOH of 4.7mm or more along with the same DBB threshold.
- The TOH-DBB index effectively captured disease changes across different stages of primary medial-type knee OA, showing promising diagnostic capability.
[Segmentation of Mass in Mammogram Using Gaze Search Patterns].

Article Synopsis
- Radiologists often struggle to detect small or hidden lesions in dense breast tissue on mammograms, leading to the use of computer-aided detection (CAD) systems to enhance image interpretation.
- This study focused on using focus images from an eye-tracking device to accurately segment masses in mammograms, involving experts and technologists analyzing both abnormal and normal cases.
- Results showed that the UNIT method outperformed others in segmentation accuracy, achieving a higher dice coefficient, indicating it is a promising approach for enhancing mammogram analysis, though further improvements and larger sample sizes are needed.
Long-term changes of choroidal blood flow velocity in Vogt-Koyanagi-Harada disease.
Graefes Arch Clin Exp Ophthalmol
June 2022
Purpose: To evaluate changes in choroidal blood flow in patients with Vogt-Koyanagi-Harada (VKH) disease after initiation of corticosteroid treatment.
Methods: Fourteen patients (10 men and 4 women) with acute VKH disease followed for 2 years were retrospectively reviewed; only right eyes were included in the analysis. Mean blur rate (MBR) in the macula was measured by laser speckle flowgraphy (LSFG) and central choroidal thickness (CCT) was measured by optical coherence tomography (OCT), both prior to treatment and over 2 years after initiation of corticosteroid treatment.
