# Common DICOM Tags Reference

This document provides a comprehensive list of commonly used DICOM tags organized by category. Tags can be accessed in pydicom using attribute notation (e.g., `ds.PatientName`) or tag tuple notation (e.g., `ds[0x0010, 0x0010]`).

## DICOM Value Representations (VR)

Common value representation types used in DICOM:

- **AE**: Application Entity (max 16 chars)
- **AS**: Age String (nnnD/W/M/Y)
- **CS**: Code String (max 16 chars)
- **DA**: Date (YYYYMMDD)
- **DS**: Decimal String
- **DT**: Date Time (YYYYMMDDHHMMSS.FFFFFF&ZZXX)
- **IS**: Integer String
- **LO**: Long String (max 64 chars)
- **LT**: Long Text (max 10240 chars)
- **PN**: Person Name
- **SH**: Short String (max 16 chars)
- **SQ**: Sequence of Items
- **ST**: Short Text (max 1024 chars)
- **TM**: Time (HHMMSS.FFFFFF)
- **UI**: Unique Identifier (UID)
- **UL**: Unsigned Long (4 bytes)
- **US**: Unsigned Short (2 bytes)
- **OB**: Other Byte String
- **OW**: Other Word String

## Usage Examples

### Accessing Tags by Name
```python
patient_name = ds.PatientName
study_date = ds.StudyDate
modality = ds.Modality
```

### Accessing Tags by Number
```python
patient_name = ds[0x0010, 0x0010].value
study_date = ds[0x0008, 0x0020].value
modality = ds[0x0008, 0x0060].value
```

### Checking if Tag Exists
```python
if hasattr(ds, 'PatientName'):
    print(ds.PatientName)

# Or using 'in' operator
if (0x0010, 0x0010) in ds:
    print(ds[0x0010, 0x0010].value)
```

### Safe Access with Default Value
```python
patient_name = getattr(ds, 'PatientName', 'Unknown')
study_desc = ds.get('StudyDescription', 'No description')
```
