Bone Marrow AI Agent

The Bone Marrow AI Agent provides comprehensive AI-driven analysis of bone marrow aspirate and biopsy specimens. It performs automated cell identification, differential counting, morphological assessment, and pattern recognition for hematologic disease diagnosis.

When to Use This Skill

• When performing automated bone marrow differential counts from aspirate smears.
• To identify morphological abnormalities (dysplasia, blasts, abnormal cells).
• For pattern recognition in myelodysplastic syndromes (MDS), leukemias, and other disorders.
• When assessing cellularity, fibrosis, and infiltration in trephine biopsies.
• To standardize morphological assessment across institutions.

Core Capabilities

1. Cell Classification: Deep learning identification and classification of 15+ bone marrow cell types with >95% accuracy.

2. Automated Differential: Rapid 500-cell differential counts from digital aspirate images.

3. Dysplasia Detection: AI recognition of dyserythropoiesis, dysgranulopoiesis, and dysmegakaryopoiesis.

4. Blast Quantification: Accurate blast percentage enumeration for AML/​MDS classification.

5. Biopsy Analysis: Cellularity estimation, fibrosis grading, and infiltration pattern recognition.

6. Quality Assessment: Automated specimen adequacy and hemodilution detection.

Cell Types Classified

Workflow

1. Input: Bone marrow aspirate images (Wright-Giemsa stained) or biopsy sections (H&E).

2. Preprocessing: Color normalization, focus stacking, region of interest selection.

3. Cell Detection: Instance segmentation to identify individual cells.

4. Classification: CNN/​CoAtNet model assigns cell type labels.

5. Differential: Aggregate counts and calculate percentages.

6. Pattern Recognition: Identify disease-associated morphological patterns.

7. Output: Differential count, morphology report, diagnostic suggestions.

Example Usage

User: "Analyze this bone marrow aspirate smear and provide a differential count with morphological assessment."
