Abstract: In a method for evaluating a connective tissue condition of a patient, an indicator of the supporting tissue condition may be generated. A portion of connective tissue of the patient is irradiated using a light source. The connective tissue may be irradiated in vivo through the skin or via an incision, for example. Alternatively, a biopsy of the connective tissue may be irradiated. Then, spectral content information for light scattered, reflected, or transmitted by the connective tissue is determined. The spectral content information is used, at least in part, to generate the indicator. The indicator may assist a physician in diagnosing or ruling out the connective tissue condition, determining a risk of developing a disease, monitoring the progression of a disease, monitoring a response to treatment, etc.

Abstract: In a method for diagnosing or helping to diagnose a bone tissue condition of a patient, a portion of bone tissue of the patient is irradiated using a light source. The bone tissue may be irradiated in vivo through the skin or via an incision, for example. Alternatively, a biopsy of the bone tissue may be irradiated. Then, spectral content information for light scattered, reflected, or transmitted by the bone tissue is determined, and is used, at least in part, to determine whether the patient has a bone tissue condition.
