# Multi-Series Support

> Working with T1/T2 and multiple MRI series

## Automatic Series Detection

When you load a folder containing multiple MRI series, ALTICIAN Spine automatically detects and separates them by Series Instance UID.

## Series Selection

If multiple series are found, a selection dialog appears:

* Each series shows its description, contrast type (T1/T2), and slice count.
* Select one or more series to load.
* T1 and T2 contrast types are automatically classified.

## Combo View

When both T1 and T2 series are loaded, the app automatically generates **Combo views**:

| Combo    | Description      |
| -------- | ---------------- |
| T2W Sag. | T2-weighted only |
| T1W Sag. | T1-weighted only |
| Ratio    | T2/T1 ratio map  |
| All      | Combined view    |

Switch between combos using the **Combo** dropdown in the toolbar.

<Tip>
  Up to 5 combo presets can be stored. Use the combo modal to create custom combinations.
