A Study to Compare How Well Gadoquatrane Works and Its Safety With an Already Available Contrast Agent for MRI in People With Any Known or Suspected Problems of the Body (Except Brain or Spinal Cord-related Problems)

Exclusion Criteria

• •Considered clinically unstable or has a concurrent/concomitant condition that may significantly alter image comparability between the 2 study MRIs or between study parameters (e.g. safety, pharmacokinetics \[PK\] parameters) or would not allow participation for the full planned study period, in the judgement of the investigator
• •Participants presenting with severe renal insufficiency, defined as an estimated glomerular filtration rate (eGFR) \< 30 mL/min/1.73 m\^2, derived from a serum or plasma creatinine sample obtained within 48 hours prior to the first contrast agent injection in the study
• •Participants with acute kidney injury (i.e., acute renal failure), regardless of eGFR
• •History of moderate to severe allergic-like reaction to any GBCA
• •Bronchial asthma considered unstable or who have had recent modification to their medical therapy
• •Receipt of any contrast agent \< 72 h prior to the study MRIs or planned to receive any contrast agent during the trial until 24 h +/- 4 h after the second study MRI
• •Planned or expected interventional diagnostic or therapeutic procedure (e.g. biopsy or surgery in the region of interest) or change in treatment (e.g. start of chemotherapy or antiangiogenic therapy, significant change in corticosteroids dose) that may significantly alter image comparability between the 2 MRIs or other study parameters (i.e. safety/adverse events \[AEs\] \[e.g. confounding AEs or safety events due to surgery or chemotherapy\], PK parameters), from the first study MRI up to 24 h after the second study MRI
• •Has received any investigational product within 30 days, or within 5 times half-life of the investigational product, whatever is shorter, prior to or concurrent with this study
• •Contraindications to the administration of macrocyclic GBCAs (depending on local product label), or history of adverse reaction to gadoquatrane
• •Any contraindication to MRI examinations based on institution policy and investigator's clinical judgement (e.g. some metallic implants or active implants)
