Gray scale image from excel pixel files

Hi so I have a massive csv/excel (340x242) file with a pixel matrix. The values range from 0 to 7786 corresponding to intensity. I'm trying to get a grayscale image of the orginal picture (the pixels correlate to an ultrasound). Once I have the image I think have to filter it based on intensity, so if you have any advice on that it would be greatly appreciated- but I'm mainly just trying to focus on getting the orginal picture right now!! Right now I'm only getting a black and white image using imshow() right now. I've attached the image I'm currently getting.

Thanks in advance!!!

Try this

grayImage = uint16(csvread(filename));
imshow(grayImage, []);

If that doesn't work, try importdata(), readtable(), readmatrix(), or dlmread(). And attach your csv file so we can give you working code.
