Perl:Read single value from text file and assign to variable

Hello All,

A part of my very basic perl code requires me to read a single value from a text file.

The file output is the following:
Code:
Reading image ... done
IMAGEREGION=0x0x0-256x162x256
VOXELDIMENSION=0.9375000000x1.2000000477x0.9375000000
VOXELNUMBER=10527001
VOXELVALUESSUM=17106334539.8829383850
VOXELVALUESMIN=0.9334983230
VOXELVALUESMAX=44340.0000000000
VOXELVALUESMEAN=1624.9960021741
VOXELVALUESMEDIAN=695.7995605469

Am trying to read value 44340 alone and assign it to a variable.

Any help will be very much appreciated.
Many thanks
N
