In that realm, there’s not a whole lot we can without actual touch with current tech.
We have handheld Portable X-Rays that are about the size of an old digital camera, but you’d probably want something with the resolution of an MR, and the smallest of those at current is about the size of a large trashcan (which is still pretty cool).
If you include basic contact with the device, we can detect Blood Oxygen, Glucose, 12-lead equivalent EKG, some hormones, some infections (rapid detection for cutaneous), and some level of internal imaging with handheld Ultrasound (low-res but live).

















You probably need a psych consult. A normal functioning human should understand and feel empathy with other human beings. You lacking that, especially the way you’re describing it, could be a sign of something else at play you should be aware of, especially if you ever plan on having normal relationships with other people and possibly children.
