Susceptibility weighted imaging (SWI), originally called BOLD venographic imaging, is an MRI sequence that is exquisitely sensitive to venous blood, hemorrhage and iron storage. SWI uses a fully flow compensated, long echo, gradient recalled echo (GRE) pulse sequence to acquire images.
In principle, any 3D gradient echo sequence can be used for data acquisition. In practice, high resolution imaging with a moderately long echo time is preferred to obtain sufficient susceptibility effects, although the optimal imaging parameters depend on the specific applications and the field strength.

Cypress Lake is a 2-acre (0.8 ha) swamp-like lake in the heart of the University of Louisiana at Lafayette campus that started as a prehistoric bison wallow. Today it is a unique university landmark that is a habitat for native irises, alligators, turtles, birds and fish, as well as a hangout for students and a point of interest for tourists visiting Lafayette, Louisiana.
The Richard K. Yancey Wildlife Management Area, formerly the Red River/Three Rivers Wildlife Management Area, is a 70,872-acre (28,681 ha) [1] tract of protected area in lower Concordia Parish, Louisiana. The area is owned by the Louisiana Department of Wildlife and Fisheries and the U.S. Army Corps of Engineers (USACOE).
Atchafalaya Basin. The wetlands of Louisiana are water-saturated coastal and swamp regions of southern Louisiana, often called "Bayou".. The Louisiana coastal zone stretches from the border of Texas to the Mississippi line [1] and comprises two wetland-dominated ecosystems, the Deltaic Plain of the Mississippi River (unit 1, 2, and 3) and the closely linked Chenier Plain (unit 4).

This waterway is known for fishing, boating, and duck hunting. Among the fish caught in Old River, crappie (known as sac-a-lait in southern Louisiana) [2] are probably the most sought after. Other fish species include bluegill, largemouth bass, several species of catfish, largemouth buffalo, and the endangered paddlefish.
In molecular biology, SWI/SNF (SWItch/Sucrose Non-Fermentable), [1] [2] is a subfamily of ATP-dependent chromatin remodeling complexes, which is found in eukaryotes. In other words, it is a group of proteins that associate to remodel the way DNA is packaged.
