Cost Comparisons Between Different Techniques of Percutaneous Renal Biopsy for Small Renal Masses

PURPOSE To compare the costs associated with ultrasound (US)-guided hospital-based (UGHB), CT-guided hospital-based (CTG), and US-guided office-based (UGOB) percutaneous renal biopsy (PRB) for small renal masses (SRMs). METHODS We retrospectively analyzed patient demographics, tumor characteristics, R.E.N.A.L. nephrometry scores, and cost data of patients undergoing PRB for SRM at our institution from May 2012 to September 2015. Cost data, including facility costs, professional fees, and pathology, were obtained from the departments of urology, radiology, and pathology. RESULTS A total of 78 patients were included in our analysis: 19, 31, and 28 UGHB, CTG, and UGOB, respectively. There was no difference in age, gender distribution, or tumor size among the three groups (p-values 0.131, 0.241, and 0.603, respectively). UGOB tumors had lower R.E.N.A.L. nephrometry scores (p=0.008). There were no differences in nondiagnostic rates between the UGHB, CTG, and UGOB groups [4 (21%), 5 (16%), and 6 (21%)] (p=0.852). There were no differences in final tumor treatment strategies utilized among the UGHB, CTG, and UGOB groups (p=0.447). There were 0, 2 (6%), and 0 complications in the UGHB, CTG, and UGOB biopsy groups. Total facility costs were

2129 for UGHB, CTG, and UGOB renal biopsy, respectively (p<0.0001). CONCLUSION For select patients with less anatomically complex, exophytic, and posteriorly located tumors, UGOB PRB provides equivalent diagnostic and complication rates while being significantly more cost-effective than either UGHB or CTG renal biopsy.

We retrospectively studied 1.5T cardiac MR images of 62 patients with various clinical indications. All patients had a stack of EKG gated segmented SSFP cine images through the LV. Semi-automated cardiac MR software (Argus) was used to trace LV contours both at multiple slices from base to apex as well as just 3 slices (base, mid and apical) by two readers. End diastolic volume (EDV), end systolic volume (ESV), stroke volume (SV), and ejection fraction (EF) were calculated using both assessment methods. Results There were no statistically significant differences between EF and LV volumes obtained by multi-slice vs 3-slice analysis for both readers (P > 0.05). For reader 1 (and 2), Bland-Altman plot revealed the mean difference in LVEF between multi-slice and 3-slice analysis was 0.4% (0.5%) with limits of agreement of -4.3% to 5.1% (-3.9% to 4.9%) (Figure 1). For both readers, all differences in EF between multi-slice and 3-slice analysis were within 5.3%. The measured volumes are listed in Table 1. Multi-slice assessment required approximately 10 minutes per study while 3-slice evaluation required about 3-5 minutes. Conclusions The LVEF obtained from either 3-slice or multi-slice evaluation of SSFP cine images closely correlate across various cardiac pathologies, thereby offering a method to reduce post-processing time. Of note, although the decreased LV volumes obtained by 3-slice segmentation are statistically significant, the difference of < 3.7% may not be clinically significant. Funding None.

Radiogenomics and IR

Care for the trauma patient requires a multidisciplinary approach with collaborative involvement between the emergency department, trauma service, interventional radiology (IR), and numerous other surgical subspecialties. IR has an established and integrated role in the non-operative management of trauma patients. Injuries related to abdominal trauma span a wide range of severity with a variety of clinical presentations and radiologic findings. Though traumatic injury to the solid organs of the abdomen historically necessitated surgical management, a significant shift to non-operative strategies has occurred over the past several decades. Non-operative management (NOM) aims for preservation of the affected organ while avoiding morbidity related to major surgery. Transarterial embolization (TAE) for injury to the spleen, liver, and kidney has become an important part of non-operative management in hemodynamically stable patients, achieving hemostasis while preserving viable tissue within the injured organ. Via specific and selective intervention, TAE has also emerged as an important adjunct for management of ongoing hemorrhage in postoperative trauma patients.

The SIR recognizes that the choice to become a parent should not prevent a physician from having a successful career in Interventional Radiology (IR), and that a successful career in Interventional Radiology should not preclude parenthood. The choice to become a parent does not diminish one’s commitment to the profession. Interventional radiologists who choose to have children, whether by pregnancy or adoption, should not face discrimination or punitive consequences of any kind. The SIR joins other medical specialty organizations that also have policy statements supporting members who choose to become parents (1,2,3).
