When a hospital plans interventional capacity, the decision of C-arm vs cath lab is really a question of scope: how complex the procedures are, how many per day and how much you can invest in a dedicated room. This guide compares a mobile C-arm with DSA against a fixed angiography system, and explains where each is appropriate for vascular and cardiology services.
What a cath lab provides that a mobile unit does not
A fixed cath lab or angiography suite has a floor- or ceiling-mounted gantry, a dedicated generator and tube designed for continuous high-load work, a motorised table, a large monitor array, a haemodynamic recording system and a shielded, ventilated room. It is built for complex coronary and structural-heart work, long procedures and high daily volumes.
These systems usually add large detectors, rotational acquisition, advanced dose management, tableside controls and integration with injectors and physiological monitors. The trade-off is space, construction cost, planning time and the need for a dedicated team.
What a mobile C-arm with DSA can do
A modern mobile C-arm with digital subtraction angiography (DSA) and roadmap covers many peripheral vascular and non-cardiac interventions at a fraction of the infrastructure. The Perlove PLX C9100 offers angiography, DSA, roadmap, fluoroscopy and radiography, a large dynamic flat panel covering the chest, abdomen or pelvis in one exposure, and circulating cooling for extended high-frame-rate fluoroscopy.
Perlove names uses such as TACE, pacemaker implantation, peripheral arteriography, inferior vena cava filter placement and ERCP. It includes a high-pressure injector interface and a tableside controller. The PLX C7100 similarly provides an injector interface that starts injection when fluoroscopy begins, and runs without ceiling mounts or floor rails.
C-arm vs angiography and DSA: a decision table
The decision depends on case mix. A mobile C-arm fits departments that do peripheral interventions, embolisation, pacing, filter placement or hybrid theatre support, or those starting a service. A fixed system fits high-volume coronary and structural-heart programmes and complex neurovascular work.
Do not choose on detector size alone. Compare frame rate, subtraction quality, table and C-arm range, cooling and heat capacity, dose reporting and the sterile-field ergonomics. Also consider whether your cases require haemodynamic monitoring, intravascular imaging or biplane capability.
- Mobile C-arm: flexible, lower infrastructure, shared between rooms
- Cath lab: dedicated room, higher throughput, advanced cardiac tools
- Hybrid OR: fixed or mobile imaging in a surgical environment
- Check case volume, staff training and referral pathways before deciding
C-arm for cath lab support and fixed fluoroscopy rooms
Many hospitals use both: a fixed room for major cardiac work and a mobile C-arm for bedside, backup and satellite procedures. A mobile C-arm is also a good backup when the main system is down for service. The Perlove PLD7600 is a different category: a ceiling-suspended dynamic DR system for radiography, fluoroscopy and partial angiography such as esophagography, pyelography and salpingography, suited to a general X-ray or fluoroscopy room rather than a coronary cath lab.
See our explanation of vascular C-arm systems and C-arm versus fluoroscopy for how the categories overlap.
Questions to ask before buying
Ask suppliers for the intended procedure list, the subtraction and roadmap performance in a live demonstration, cooling and duty cycle for long cases, injector compatibility, DICOM and dose reporting, and the service model in the UAE. Confirm radiation shielding and licensing needs with the authorities, as requirements differ between emirates and change over time.

Frequently asked questions
Can a mobile C-arm replace a cath lab?
For many peripheral and non-cardiac interventions, yes. For complex coronary, structural-heart and high-volume programmes, a fixed system with a dedicated room and advanced tools is generally preferred.
Does a C-arm offer DSA?
Some models do. The Perlove PLX C9100 provides DSA and roadmap, and the PLX C7100 provides DSA subtraction imaging. Check the option list for any model.
What is the difference between DSA and fluoroscopy?
Fluoroscopy shows live images, while DSA subtracts a pre-contrast mask image to show the vessels clearly. Roadmap overlays the vessel map on live fluoroscopy to guide the catheter.
Can a C-arm be used in a hybrid operating room?
Yes, mobile C-arms are widely used in surgical theatres and hybrid environments. The room still needs proper shielding, power and workflow planning.
