The fluid verification module includes a body defining an inlet port, an outlet port, and a fluid channel extending from the inlet port to the outlet port; a first tubing section connected to the inlet port; and a second tubing section connected to the outlet port. ## Claims ### Claim 1 An administration line for use with a fluid injector system, the administration line comprising: a fluid verification module configured to be in operative communication with a housing of the fluid injector system such that the fluid injector system can determine a status of the administration line, the fluid verification module comprising: a body defining an inlet port, an outlet port, a fluid channel extending from the inlet port to the outlet port, and a priming port in fluid communication with a priming cavity; a first tubing section connected to the inlet port; and a second tubing section connected to the outlet port, wherein the second tubing section comprises an outlet fitting configured to connect to the priming port during storage or shipment of the administration line, and wherein the priming cavity is configured to receive and hold priming fluid from the outlet fitting during a priming operation of the administration line. ### Claim 2 (depends on 1) The administration line of claim 1, wherein the first tubing section comprises: a first inlet fitting configured for connection to a first fluid reservoir of the fluid injector system; and a second inlet fitting configured for connection to a second fluid reservoir of the fluid injector system, wherein the first inlet fitting is configured to connect to the second inlet fitting during storage or shipment of the administration line. ### Claim 3 (depends on 1) The administration line of claim 1, wherein the first tubing section comprises: an inlet fitting configured for connection to an intermediate tubing set in fluid communication with at least one fluid reservoir of the fluid injector system, wherein the inlet fitting is configured to connect to the body of the fluid verification module during storage or shipment of the administration line. ### Claim 4 (depends on 1) The administration line of claim 1, further comprising at least one sheet material disposed within the priming cavity, the at least one sheet material comprising: a first sheet material having indicia; and a second sheet material which transitions from an opaque state to an at least partially translucent state when the second sheet material is contacted by the priming fluid, wherein the indicia on the first sheet material is obstructed by the second sheet material when the second sheet material is in the opaque state, and wherein the indicia on the first sheet material is visible via a window in the body when the second sheet material is in the translucent state. ### Claim 5 (depends on 1) The administration line of claim 1, further comprising at least one sheet material disposed within the priming cavity, wherein the at least one sheet material is configured to change in electrical resistance when contacted by the priming fluid, and wherein, when the fluid verification module is mounted to the housing of the fluid injector system, the at least one sheet material is configured to interface with at least one probe of the fluid injector system for measuring electrical resistance of the at least one sheet material. ### Claim 6 (depends on 1) The administration line of claim 1, wherein the body of the fluid verification module further comprises a capillary channel in fluid communication with the priming cavity and configured to take up at least a portion of the priming fluid via capillary action. ### Claim 7 (depends on 1) The administration line of claim 1, wherein at least a portion of the body of the fluid verification module is configured to act as a lens to display light emitted from a light source of the fluid injector system. ### Claim 8 (depends on 1) The administration line of claim 1, wherein the body of the fluid verification module comprises one or more engagement features configured for securing the fluid verification module to the housing of the fluid injector system. ### Claim 9 (depends on 1) The administration line of claim 1, wherein the fluid channel is at least partially transparent such that an imaging device of the housing can determine the presence or absence of fluid in the fluid channel. ### Claim 10 (depends on 1) The administration line of claim 1, wherein the fluid channel is flexible and configured to interface with a strain gauge of the housing such that the strain gauge can determine fluid pressure in the administration line. ### Claim 11 (depends on 1) The administration line of claim 1, further comprising at least one of: an inlet one-way valve associated with the inlet port; and an outlet one-way valve associated with the outlet port, wherein at least one of the inlet one-way valve and the outlet one-way valve prohibit fluid flow in an upstream direction from the second tubing section toward the first tubing section. ### Claim 12 A fluid injector system configured to perform an injection procedure in connection with a diagnostic imaging procedure, the fluid injector system comprising: an administration line comprising: a fluid verification module, the fluid verification module comprising a body defining an inlet port, an outlet port, a fluid channel extending from the inlet port to the outlet port, and a priming port in fluid communication with a priming cavity; a first tubing section connected to the inlet port; and a second tubing section connected to the outlet port, wherein the second tubing section comprises an outlet fitting configured to connect to the priming port during storage or shipment of the administration line, and wherein the priming cavity is configured to receive and hold priming fluid from the outlet fitting during a priming operation of the administration line; and a controller programmed or configured to determine a status of the administration line. ### Claim 13 (depends on 12) The fluid injector system of claim 12, wherein the first tubing section comprises: a first inlet fitting configured for connection to a first fluid reservoir of the fluid injector system; and a second inlet fitting configured for connection to a second fluid reservoir of the fluid injector system, wherein the first inlet fitting is configured to connect to the second inlet fitting during storage or shipment of the administration line. ### Claim 14 (depends on 12) The fluid injector system of claim 12, wherein the first tubing section comprises: an inlet fitting configured for connection to an intermediate tubing set in fluid communication with at least one fluid reservoir of the fluid injector system, wherein the inlet fitting is configured to connect to the body of the fluid verification module during storage or shipment of the administration line. ### Claim 15 (depends on 12) The fluid injector system of claim 12, further comprising: at least one probe for measuring electrical resistance in communication with the controller;
