Comparison of various methods for cardiovascular studies in terms of analysis depth, resolution, and scan time. Raman and surface enhanced Raman spectroscopy (SERS) provide the highest resolution and shortest scan time. However, conventional methods like MRI and CT show the greatest depth of analysis. FTIR, Fourier-transform infrared spectroscopy; MRI, magnetic resonance imaging; CT, computed tomography; PET, positron emission tomography; SPECT, single-photon emission computerized tomography; NIRF, near infrared fluorescence.
