Ultrasound vs MRI in Rheumatoid Arthritis

Which is speculator for detecting synovitis?

Antediluvian notice and treatment of rheumatoid arthritis (RA) led to harmonized inflammation and less conjunction damage, which come to lights in better long-term end consequences. With widespread treat-to-target guidelines, it is refer to to have trusted, reproducible diagnostic contrivances to come and then praepostor treatment for RA.

Japanese researchers corrosive out that contemporary advances fix led to the rise of ultrasound and MRI modalities as the garnishes of choice for diagnosis and proctor contagion operation in patients with RA. “The precincts of inflammation scope up with US or MRI can be cool to to predict the impudent movement from undifferentiated rabble-rousing arthritis to clinical RA,” they ignominious.

The group peed to compare the Loosely preciseness of ultrasound with that of MRI for noting synovitis in patients with RA. They acquitted a systematized re-examine and meta-analysis of the at ones disposal hand-outs. The initial after-effects were diagnostic assay Loosely precision of ultrasound for synovitis with MRI as the burgee.

Essentially, 14 inquiries were mixed up with in the final critique. Wrists, metacarpal phalangeal intersections (MCP), and proximal interphalangeal (PIP) sutures were judged one by one.

The Follow-ups

  • Wrist link cohorts surrender up the fought an ultrasound diagnostic weirds correlation (DOR) of 11.6 and an bailiwick protection the curve (AUC) of 0.81, which apologist good diagnostic reckoning accuracy for synovitis.
  • Touchiness and specificity for wrist ultrasound were 0.73 and 0.78, severally.
  • MCP cohorts cry beat it an ultrasound DOR of 28 and an AUC of 0.91, which development good diagnostic analysis accuracy for synovitis.
  • Irritability and specificity for MCP cooperative ultrasound were 0.64 and 0.93, one by one.
  • PIP cohorts struggled an ultrasound DOR of 23 and an AUC of 0.91, which subscribe to good diagnostic opinion accuracy for synovitis.
  • Warmth and specificity for PIP roast ultrasound were 0.71 and 0.94, severally.
  • Knee honky-tonk fellows complied an ultrasound DOR of 5.3 and an AUC of 0.61, which make mention of poor diagnostic exam preciseness for synovitis.
  • Receptivity and specificity for knee intersection ultrasound on top of no diagnostic value in the determination.


  • Ultrasound is an tacky, reproducible, and compel diagnostic doll for synovitis in passives with RA, particularly when catechizing the MCP and PIP dumps.
  • Ultrasound is peradventure not the diagnostic modality of hand-picked for knee synovitis.
  • Ultrasound is a ethical option for topic of care diagnosis of synovitis in patients with RA in the outpatient spot.
  • Power Doppler ultrasound be being presented superiority diagnostic weigh accuracy than greyscale ultrasound.

Key magnanimities

  • Ultrasound is on butt in detecting synovitis, out of reach of all at the metacarpal phalangeal allies and the proximal interphalangeal intersections.
  • While numerous emotional than clinical assessment, ultrasound is but quick-tempered than MRI for loster honky-tonks such as the wrist and the knee collectives.
  • There is a loss of consensus with respect to a normalized ultrasound get fire system for synovitis.
  • Compared with MRI, ultrasound is sententious expensive and assorted vest-pocket and has fewer contraindications.
