 We mine image-paired report to extract findings on diverse anatomy structures, and quantify the multi-grained image-image relevance via [RaTEScore](https://arxiv.org/abs/2406.16845). 
 Specifically, we have extended two public datasets for multi-grained medical image retrieval task:
-- MIMIC-IR is extended from [MIMIC-CXR](https://physionet.org/content/mimic-cxr/2.1.0/), containing 377,110 images and x anatomy structures.
+- MIMIC-IR is extended from [MIMIC-CXR](https://physionet.org/content/mimic-cxr/2.1.0/), containing 377,110 images and 90 anatomy structures.
 - CTRATE-IR is extended from [CTRATE](https://huggingface.co/datasets/ibrahimhamamci/CT-RATE), containing 25,692 images and 48 anatomy structures.
 
-A simple demo to read the data from CTRATE-IR:
+**Note:** For the MIMIC-IR dataset, you need to manually merge and decompress the files.  
+After downloading all split parts (from `MIMIC-IR.tar.gz.part00` to `MIMIC-IR.tar.gz.part08`), execute the following commands in the same directory:
+```
+cat MIMIC-IR.tar.gz.part* > MIMIC-IR.tar.gz
+tar xvzf MIMIC-IR.tar.gz
 ```

 print(f'Relevance score: {simi_tab[sample_A_idx, sample_B_idx]}')
 ```
 
 Note that the score have been normalized to 0~100 and stored in uint8. We also provide the whole image-level relevance quantified based on their entire reports:
