Adding Local Flavor to World Class Imaging1

Carl L. Kalbhen, MD

1 From Northwest Radiology Associates, 800 W Central Rd, Arlington Heights, IL 60005. From the Opening Session of the 2006 RSNA Annual Meeting. Received May 30, 2007; revision requested May 31 and received June 4; accepted June 4. The author has no financial relationships to disclose.

  		Figure 1.  Chicago-style deep dish pizza. Uninfused sagittal T2-weighted MR image shows the high signal intensity of the water-rich tomato sauce and toppings (black *) on top of the medium signal intensity of the cheese (arrowhead), both sitting atop the near signal void of the crust (white *). Note the thickness of each layer as well as the fact that the tomato sauce and toppings are above the cheese, features that would not be seen on an MR image of a traditional pizza.

  		Figure 2.  Italian beef sandwich with sweet peppers. Uninfused coronal T2-weighted MR image shows the bright signal intensity of the beef juices soaking into what would otherwise be the signal void of the Italian roll (arrowheads). Mostly because of these juices, the beef itself is of heterogeneous medium signal intensity (white *), with the water-rich, sliced, and sautéed green peppers appearing as bright crescents atop the entire sandwich (black *).

  		Figure 3.  Chicago-style hot dog with everything. Uninfused axial T2-weighted MR image shows the mildly heterogeneous (more intense peripherally than centrally) signal intensity of the hot dog itself (*). It sits within the essential signal void of a poppy seed bun, with the standard water-rich toppings surrounding the "puppy" as irregularly shaped bands of bright signal intensity (arrows). Please note the absence of ketchup.

  		Figure 4.  Ripe, red multilocular tomato. Uninfused axial T2-weighted MR image exquisitely depicts the relevant anatomy. This section contains eight separate fluid-rich locular cavities (black arrows). The more fibrous—and heterogeneously darker signal intensity—columella is at the center (*). Individual small rounded vascular bundles (white arrow) can be seen throughout the outer wall of the pericarp.

  		Figure 5.  Gala apple. Uninfused coronal T2-weighted MR image shows heterogeneity of signal intensity within the cortex, with areas specifically having focal loss of the expected bright signal intensity (*). This finding perhaps results from a magnetic susceptibility artifact caused by iron within the apple’s skin. The apple’s core (arrows) is nearly void of signal, as it contains minimal water.

  		Figure 6.  Corn on the cob. Uninfused sagittal T2-weighted MR image through the center of the corncob shows numerous well-circumscribed areas of increased signal intensity (black arrow) representing the individual corn kernels. The relatively fibrous inner cob (*) has comparatively less increased signal intensity. The entire corn ear is surrounded by a thick husk (white arrow).

  		Figure 7.  Six-ounce container of strawberry banana yogurt with fruit. Uninfused coronal T2-weighted MR image reveals the medium signal intensity of the yogurt itself (white *). The high-signal-intensity fruit, of which there is an obvious paucity, appears at the bottom of the container (black *).

  		Figure 8.  Broccoli. Uninfused coronal T2-weighted MR image reveals the disgusting "tree-like" part (*) of this vile vegetable, as well as the equally unappetizing "leafy" portions (arrows).

  		Figure 9.  Rainbow trout. Uninfused sagittal T2-weighted MR image reveals the bright signal intensity of the fish musculature (black *). The fish is not perfectly linear with respect to the imaging plane, and the more peripheral scales (white *) become visible dorsally near the tail. Similarly, toward the head, the right eye (arrowhead) is seen. Removal of the fish’s head before serving is advised but by no means required.

  		Figure 10.  Foie gras. Uninfused axial T1-weighted MR image reveals diffusely increased signal intensity suggestive of, but not diagnostic for, the presence of fat. Signal voids are present within the hepatic vasculature (arrows).

  		Figure 11.  Foie gras. Uninfused axial multidetector CT image helps confirm fatty hepatic metamorphosis, as the attenuation within the oval ROI ranges from –28 to –1 HU (mean, –14.7 HU). There is very low attenuation in the portal vasculature (arrows), as there is no blood within this goose liver following force-feeding and procurement.
