Four axial spondyloarthritis (AxSpA) patients with monosodium urate <t>(MSU)</t> crystal and radiographic structural damage at the sacroiliac joint. For each set of images, panel a shows the sacroiliac joint on plain radiographs, panel b shows the three-dimensional reconstruction dual-energy computed tomography <t>(DECT)</t> images, panel c shows the corresponding coronal (patient 2 and 4) or axial (patient 1 and 3) DECT images, and panel d shows the corresponding level of computed tomography (CT) images. A large quantity of MSU crystal deposition shown as green was found at the sacroiliac joint or the surrounding area in the DECT images. Four male patients (patient 1–4), aged 36, 44, 23, and 27 years old, had serum uric acid levels of 407 μmol/L, 370 μmol/L, 572 μmol/L, and 464 μmol/L, respectively. They were graded with a scale of 0, 0, II, III at the left sacroiliac joint and 0, I, II, III at the right sacroiliac joint, respectively, on plain radiographs

( a ) Optimization of the orientation angle of the linear polarizer ( γ ). The normalized output amplitude is plotted as a function of the sample fast-axis orientation, α , for different linear polarizer orientations ( γ = 50°, 55°, 65°, 75°). ( b ) The simulated normalized output images of MSU crystals at varying orientations, using γ = 65°. The MSU crystals are simulated as cylinders with a birefringence of | Δ n| = 0.1, diameter of 0.5 μm, length of 10 μm, and the fast axis is along the long axis of the crystals.

( b ) Simulated image of a MSU crystal with larger diameter (2 μm) compared to Figs 4 and 5 . The effect of the nonlinearity is manifested by the hollow appearance of the simulated images. Nevertheless, the intense (bright/dark) edges provide enough contrast for crystal detection and identification.

Clearly the crystals oriented close to 45° (see orientation guide in the bottom left) appear brighter than the background, and those close to 135° appear darker. ( c–e ) Lens-free grayscale differential image of 3 ROIs taken from ( b ). ( f–h ) Pseudo-colored images of ( c–e ). ( i–k ) 40× 0.75NA CPLM images of the same regions as ( f–h ). White arrows: crystals that result in a weak signature have better contrast in the lens-free pseudo-color images ( f,g ) than the CPLM images ( i,j ). Yellow arrows: thick MSU crystals in the lens-free pseudo-color image ( h ) have hollow appearances, slightly different from the CPLM image ( k ).

    Figure Lengend Snippet: Four axial spondyloarthritis (AxSpA) patients with monosodium urate (MSU) crystal and radiographic structural damage at the sacroiliac joint. For each set of images, panel a shows the sacroiliac joint on plain radiographs, panel b shows the three-dimensional reconstruction dual-energy computed tomography (DECT) images, panel c shows the corresponding coronal (patient 2 and 4) or axial (patient 1 and 3) DECT images, and panel d shows the corresponding level of computed tomography (CT) images. A large quantity of MSU crystal deposition shown as green was found at the sacroiliac joint or the surrounding area in the DECT images. Four male patients (patient 1–4), aged 36, 44, 23, and 27 years old, had serum uric acid levels of 407 μmol/L, 370 μmol/L, 572 μmol/L, and 464 μmol/L, respectively. They were graded with a scale of 0, 0, II, III at the left sacroiliac joint and 0, I, II, III at the right sacroiliac joint, respectively, on plain radiographs

    ( a ) Optimization of the orientation angle of the linear polarizer ( γ ). The normalized output amplitude is plotted as a function of the sample fast-axis orientation, α , for different linear polarizer orientations ( γ = 50°, 55°, 65°, 75°). ( b ) The simulated normalized output images of MSU crystals at varying orientations, using γ = 65°. The MSU crystals are simulated as cylinders with a birefringence of | Δ n| = 0.1, diameter of 0.5 μm, length of 10 μm, and the fast axis is along the long axis of the crystals.

    Article Snippet: Moreover, the red curve is almost symmetrically distributed around unity, and thus, the brighter-than-background orientations of the MSU crystal roughly correspond to 0° <α < 90°, whereas the darker-than-background orientations of the MSU crystal roughly correspond to 90° <α < 180°.

    Techniques:

    ( a ) Simulation of the differential output as a function of the relative phase retardation φ , with the crystals aligned at 45° ( α = 45°). almost linearly reaches to the maximum/minimum when |φ| increases from 0 to ~ 0.22π, then turns backwards towards 0 as |φ| further increases to π. ( b ) Simulated image of a MSU crystal with larger diameter (2 μm) compared to Figs 4 and 5 . The effect of the nonlinearity is manifested by the hollow appearance of the simulated images. Nevertheless, the intense (bright/dark) edges provide enough contrast for crystal detection and identification.

    Techniques:

    Experimental imaging result of a MSU crystal sample from a patient’s tophus, compared to a 40× 0.75NA CPLM. ( a ) The full FOV of the lens-free hologram is 20.5 mm 2 which is ~2 orders of magnitude larger compared to the FOV of a typical 40× microscope objective lens (see yellow dashed circle). ( b ) A sub-region showing the lens-free differential polarized image. Clearly the crystals oriented close to 45° (see orientation guide in the bottom left) appear brighter than the background, and those close to 135° appear darker. ( c–e ) Lens-free grayscale differential image of 3 ROIs taken from ( b ). ( f–h ) Pseudo-colored images of ( c–e ). ( i–k ) 40× 0.75NA CPLM images of the same regions as ( f–h ). White arrows: crystals that result in a weak signature have better contrast in the lens-free pseudo-color images ( f,g ) than the CPLM images ( i,j ). Yellow arrows: thick MSU crystals in the lens-free pseudo-color image ( h ) have hollow appearances, slightly different from the CPLM image ( k ).

    Article Snippet: In order to detect birefringence as well as its sign (+/−) similar to a CPLM image, ideally the brightness in the output image should vary when the MSU crystal takes different orientations in the sample FOV.
