Stethoscopes are an example where tech can help and is helping. Some sounds (a slightly leaky heart valve, say) are subtle and easily missed, especially if there is traffic outside the doctor's surgery or other noise. Even with good earpieces.

A stethoscope with microphone, analog-to-digital conversion, and digital signal processing can separate out heart sounds from lung sounds and amplify each separately, and AI analysis can learn to identify early stage problems that doctors can't yet hear.

Of course the downside of that may be a loss of skill, as we see happening with ECGs. The ECG analysis algorithms are so good now that lots of doctors don't even bother with anything more than a glance at the waveform, they just look at the text the algo provides. Understandable, when you're near the end of a 12-hour shift.

But potentially, AI based home diagnostic kits with these sorts of devices could save doctors' time.
