Diagnosing Depression

I?ve read about SPECT tests used in the diagnosis of depression, besides the mental examination of course. How reliable are they? Why aren?t they widely used yet? Are there any other reliable physical examinations or brain imaging techniques that could verify that someone is depressed? And how can I trust a diagnosis that is solely based on a conversation, no matter how long and/or extensive it is and even after ruling out other causes through physical examinations?
