An MR Spectroscopy (MRS) system and approach is provided for diagnosing painful and non-painful discs in chronic, severe low back pain patients (DDD-MRS). A DDD-MRS pulse sequence generates and acquires DDD-MRS spectra within intervertebral disc nuclei for later signal processing & diagnostic analysis. An interfacing DDD-MRS signal processor receives output signals of the DDD-MRS spectra acquired and is configured to optimize signal-to-noise ratio (SNR) by an automated system that selectively conducts optimal channel selection, phase and frequency correction, and frame editing as appropriate for a given acquisition series. A diagnostic processor calculates a diagnostic value for the disc based upon a weighted factor set of criteria that uses MRS data extracted from the acquired and processed MRS spectra along regions associated with multiple chemicals that have been correlated to painful vs. non-painful discs. A diagnostic display provides a scaled, color coded legend and indication of results for each disc analyzed as an overlay onto a mid-sagittal T2-weighted MRI image of the lumbar spine for the patient being diagnosed. Clinical application of the embodiments provides a non-invasive, objective, pain-free, reliable approach for diagnosing painful vs. non-painful discs by simply extending and enhancing the utility of otherwise standard MRI exams of the lumbar spine.

Adaptive lithotripsy systems assist diagnosis and treatment of patients with kidney stones (stones being associated with subsequent development of cancer). As stimulation vibration is transmitted to the patient, both its total transmitted power and power spectral density (PSD) are tailored to individual patient needs. One such need is for progressive stone fragmentation (a hallmark of adaptive lithotripsy systems) at minimum power levels. And minimum power levels are achieved through two adaptive mechanisms for shifting PSD to concentrate transmitted vibration power in more effective frequency ranges. This concentration necessarily reduces power in relatively ineffective ranges, thus minimizing collateral tissue damage. Effective ranges for vibration power concentration are estimated in near-real time using backscatter vibration that is retransmitted from resonating stones while encoding information on the stones' existence, size and composition. Backscatter vibration thus informs adaptive tailoring of stimulation vibration for lithotripsy that is (1) relatively safer and (2) more efficient.
