In Philips 2025 et al., on radiographic IAIP detection, how did implants placed 2 mm into the joint perform in terms of accurate classification?
🔍 Key Findings
Overall accuracy of radiography to detect IAIP: 77.9%
Sensitivity: 97.2%
Specificity: 67.6%
False positive rate: 32.4% of non-penetrating implants were misclassified as penetrating
Implants directed toward the lateral tibial condyle had higher misclassification (23.8%) than medial (8.3%)
Most accurate detection: Implants placed 2 mm into the joint (97.2% correct classification)
Least agreement: For implants placed at 0 mm (subchondral level), especially lateral (AC1 = 0.48)
No palpable abnormalities (e.g., crepitus) observed during ROM for any group
No significant difference in detection by specialty field or reviewer qualification
Suggests radiographic misclassification risk and supports considering CT/fluoroscopy in equivocal cases

In Larose 2024 et al., on fluorescence cholangiography, what timing of fluorescence onset was typical after ICG administration?
🔍 Key Findings
- Near-infrared fluorescence cholangiography (NIRFC) was feasible and safe in all healthy dogs studied, with no major adverse effects noted.
- Low-dose ICG (0.05 mg/kg) at 3 h pre-op achieved the highest target-to-background (cystic duct-to-liver) contrast ratio, reaching nearly 4:1 at 280 minutes.
- Early imaging (time 0) favored low-dose ICG for optimal cystic duct visualization; high-dose ICG led to excessive liver fluorescence and reduced contrast.
- Visualization of biliary tree occurred within 10–20 min post-injection regardless of dose, but longer delays improved background clearance and contrast.
- No significant cardiovascular or histamine-related side effects were observed with either dose of ICG.
- Repeated ICG injections showed minimal residual fluorescence when using a >72 h washout period; shorter intervals caused mild carryover in high-dose groups.
- Surgeon scoring matched contrast ratios, confirming clinical relevance of imaging outcomes.
- Recommended dose for laparoscopic imaging: 0.05 mg/kg ICG given 3–5 h before surgery, or at premedication for urgent cases.

In Knudsen 2024 et al., on CTA diagnostic accuracy, what was the combined sensitivity and specificity range in the second reading?
🔍 Key Findings Summary
- Study Design: Prospective case series of 52 scans from 44 dogs with CCL injury.
- Main Technique: 16-slice CTA; evaluated by 3 observers with varying experience; validated against surgical mini-medial arthrotomy findings.
- Diagnostic Metrics (Reading 2):
- Sensitivity: 1.00 (Observers 1 & 2), 0.93 (Observer 3)
- Specificity: 0.78–0.91
- Positive Likelihood Ratio: Up to 10.71
- Negative Likelihood Ratio: As low as 0.08
- Accuracy: 90%+ for all in Reading 2
- Observer Effect: Significant improvement between first and second reading for less experienced observers (p < 0.05); learning curve evident.
- Meniscal lesions found:
- 9/12 in suspected late meniscal injury cases
- 19/40 in newly diagnosed CCL cases
- Most common = bucket handle tears
- Conclusion: Multidetector CTA is a clinically useful, non-invasive tool for identifying medial meniscal lesions in dogs with CCL disease.

In Healy 2025 et al., on incidental PBBs, what was the observed rate of spontaneous pneumothorax in dogs during follow-up?
🔍 Key Findings
Population: 2,178 canine CTs reviewed retrospectively.
Prevalence: Incidental PBBs found in 1.37% (30/2178).
Outcome: None of the dogs with incidental PBBs developed clinical spontaneous pneumothorax (SP) over a median follow-up of 1255 days.
Significant Associations:
- Age: Dogs with PBBs were significantly older (median 10.5 yrs vs. 8.2 yrs, p = .001).
- CT indication: PBBs more likely during neoplastic staging (p = .006).
PBB Characteristics:
- Total = 60 PBBs (median 1/dog; range 1–7).
- Location: 35% in left caudal, 31.6% right caudal, only 13.3% in right cranial lobe.
- Size-based: 25 bullae (>10 mm), 35 blebs (≤10 mm).
Conclusion: Prophylactic resection of incidental PBBs not justified given no observed SP risk in this population.

In Holman 2024 et al., on lateral arthroscopy of the canine shoulder, what percentage of the medial glenohumeral ligament’s cranial border was visible?
🔍 Key Findings
- 48% of the intra-articular biceps tendon was visible at a standing angle; this increased to 63% in flexion (p = 0.0003).
- 58% of the medial glenohumeral ligament's cranial border was within view.
- 20% of the subscapularis tendon was visualized via the standard lateral arthroscopic approach.
- Visibility was assessed using tattoo ink markers and confirmed via dissection in cadavers.
- Limitations of standard lateral portals may lead to underdiagnosis of deeper or distal pathology in these structures.

In Klever 2024 et al., what effect does a dorsoventral projection have on Norberg angle measurements?
🔍 Key Findings
- Dorsoventral radiographs artificially increase Norberg angle values by 3.2–5.8% and should be excluded.
- Lateral pelvic tilt >2° causes asymmetric changes in Norberg angle; >3° results in significant side-specific changes.
- Cranioventral-to-caudodorsal tilt >10° results in obvious radiographic tilt, but changes Norberg angle by only ~2%.
- Tilted but subjectively acceptable images have minor impact and may still be usable for screening.
- Norberg angle readings differed consistently between left/right hips — possibly due to operator handedness.

In Mattioli 2025 et al., on lymphadenectomy complications, which lymph node sites were associated with a higher complication rate when surgery exceeded 21.5 minutes?
🔍 Key Findings
Sample: 201 lymphadenectomies in 163 dogs.
Intraoperative techniques:
- Unassisted: 36%
- Methylene blue (MB): 24%
- Gamma probe + MB (γ-MB): 40%
Complication rate: 7.5% overall (93% uncomplicated)
- 80% were mild, 20% moderate; no severe complications
- Most common = seroma (2.5%), lymphoedema (1.5%)
Risk factors (via decision tree model):
- Surgical time > 21.5 min
- Lymph node site = mandibular or retropharyngeal
No significant difference in complication rate based on:
- Guidance technique (p = .255)
- LN palpability, number removed, or LN size
Clinical implication: Peripheral SLN excision is safe regardless of intraoperative technique; certain sites and durations carry slightly higher risk.

In García 2025 et al., on TIAS shunt confirmation, which imaging method was NOT required during the procedure?
🔍 Key Findings
- 40 dogs with congenital EHPSS were surgically treated using intraoperative transsplenic injection of agitated saline (TIAS) to assess full temporary occlusion.
- TIAS was successful in 38/40 dogs; the remaining 2 had additional shunting vessels not originally seen and required further identification/ligation.
- No intraoperative or postoperative complications occurred.
- TIAS allowed real-time confirmation of attenuation success using ultrasound-visible microbubbles.
- Median postoperative bile acids were 5 μmol/L (preprandial) and 25 μmol/L (postprandial).
- Long-term outcomes: 29/39 dogs had excellent, 10/39 had good outcomes; 3 dogs died unrelated to EHPSS.
- Technique is presented as a safe, quick, low-cost, accessible intraoperative assessment alternative to IOMP or SP.
