I have built a PyQt5, Python 3.7 windows application that uses PyQtGraph to 
view monochrome (greyscale) Magnetic Resonance DICOM images. As I move the 
mouse pointer over the image, I would like to display the value of the 
pixel under the pointer on the window. There is no obvious (to me) 
functionality in PyQtGraph to do this. I would be very grateful for any 
suggestions by more experienced developers of how to do this. Here is an 
edited code segment showing how I display the image (pixelArray) in an MDI 
subwindow.

layout = QVBoxLayout()
widget = QWidget()
widget.setLayout(layout)
self.subWindow.setWidget(widget) 

imageViewer = pg.GraphicsLayoutWidget()
viewBox = imageViewer.addViewBox()
image= pg.ImageItem(border='w')
viewBox.addItem(image)
imageView = pg.ImageView(view=viewBox, imageItem=image)
layout.addWidget(imageView)
imageView.setImage(pixelArray)
