MonoGame, sprite to rectangle

I'm working with MonoGame in VB2015 - please don't give answers that involve using C#.

Anyway, I found a snippet which I converted to VB for pixel collision. The function below accepts two rectangles, then runs a pixel check on the intersection between the two.

What I can't work out is how to send my two sprites (textures) to the function as rectangles. Or if anyone has a alternative, please let me know.

  Private Shared Function IntersectPixels(rectangleA As Rectangle, dataA As Color(), rectangleB As Rectangle, dataB As Color()) As Boolean
' Find the bounds of the rectangle intersection
Dim top As Integer = Math.Max(rectangleA.Top, rectangleB.Top)
Dim bottom As Integer = Math.Min(rectangleA.Bottom, rectangleB.Bottom)
Dim left As Integer = Math.Max(rectangleA.Left, rectangleB.Left)
Dim right As Integer = Math.Min(rectangleA.Right, rectangleB.Right)


(No, this isn't the whole routine...)

Dim textureRect as Rectangle = new Rectangle(CType(position.x, integer), CType(position.x, integer), texture.Width, texture.Height);
