CT Scan with Contrast

Contrast-enhanced multi-slice CT at SurGal Clinic Brno using AIDR low-dose technology. Intravenous contrast improves soft-tissue characterisation and vascular detail for tumour, infection, or vascular indications.

Contrast-enhanced CT at SurGal Clinic Brno adds intravenous iodinated contrast agent to the standard imaging protocol, enhancing the visibility of vascular structures, soft-tissue lesions, lymph nodes, and actively perfused tissues. The contrast agent is administered via peripheral intravenous cannula and the scan is timed to capture the optimal enhancement phase for the clinical question — arterial phase for vascular pathology, portal venous phase for liver and abdominal organs, or multi-phase acquisition for complex lesion characterisation. The CT department uses AIDR (Adaptive Iterative Dose Reduction) software, which keeps radiation exposure 50–80% lower than conventional CT protocols. This means that even contrast-enhanced studies, which sometimes require multi-phase acquisitions, remain within substantially lower dose ranges than older technology would produce — particularly valuable for patients with conditions requiring regular imaging surveillance. Contrast-enhanced CT is indicated for a wide range of clinical scenarios: staging of known or suspected malignancy (where contrast reveals metastatic deposits and defines tumour margins), detection of inflammatory masses and abscesses, evaluation of vascular anatomy before surgery, pulmonary embolism investigation (CT pulmonary angiography), assessment of acute aortic pathology, and post-operative follow-up to monitor for complications or disease recurrence. The radiology team at SurGal — led by prim. MUDr. Lukáš Hruška — assesses each patient for contraindications to iodinated contrast: allergy history, renal function (creatinine levels), and concurrent medications (particularly metformin, which requires a temporary pause after contrast administration). Pre-examination hydration instructions are provided. For patients with documented contrast allergy, premedication with corticosteroids can be arranged. Self-pay and foreign patients book through the SurGal Premium portal. Reports are provided in written form. The department is contracted with all Czech public health insurers.
