# Medical Vlm Eval

> Evaluates a vision-language model's ability to localize tumors in medical images and generate structured clinical reports. Probes spatial accuracy of coordinate prediction and the clinical utility/quality of automated radiology reports. Use when the user wants to benchmark on Unspecified medical imaging dataset, or asks about evaluating this task. Reports positional_deviation.

## What this evaluates

Evaluates a vision-language model's ability to localize tumors in medical images and generate structured clinical reports. Probes spatial accuracy of coordinate prediction and the clinical utility/quality of automated radiology reports.

## Datasets

- **Unspecified medical imaging dataset** — total ?; splits: test (-1)

## Metrics

- `positional_deviation` **(primary)** — range: pixels
  - Absolute difference between predicted and reference tumor coordinates in pixels. Lower values indicate better spatial localization.
- `confidence_score` — range: 1 to 10
  - Certainty rating for each detected abnormality, scaled from 1 to 10 based on lesion clarity and boundary definition.

## Input / output format

**Input**: Medical images (CT, MRI, X-ray, ultrasound) provided to a VLM.

**Output**: JSON object containing tumor location coordinates and metadata; structured clinical report with examination details, anatomical region, findings, and confidence scores (1-10).

## Scoring recipe

```python
def compute_coordinate_accuracy(pred_coords, ref_coords):
    return abs(pred_coords - ref_coords)  # in pixels

def compute_report_quality(report):
    # Multi-dimensional qualitative assessment: structural completeness, clinical accuracy, technical precision, adherence to standards
    return qualitative_rubric_score(report)
```

## Common pitfalls

- Performance degrades in complex multi-pathology cases with overlapping abnormalities.
- Confidence scores may not perfectly correlate with actual diagnostic accuracy for subtle or ambiguous findings.
- Lack of standardized dataset and splits makes cross-study comparison difficult.

## Evidence (verbatim from paper)

> Overall positional deviations were reduced to within approximately ±80 pixels of the original location in the tested cases, demonstrating consistent and reliable performance across the evaluated dataset. Each identified abnormality receives a confidence score ranging from 1 to 10, offering clinicians quantitative measures of diagnostic certainty.
