Abstract

Aim: The aim of our study was to assess the diagnostic
value of biplanar ultrasonography in detecting degenerative changes of femoral
articular cartilage using magnetic resonance imaging as the reference method.

Material
and Methods: Femoral articular cartilage examination was performed
with ultrasonography and magnetic resonance imaging in 40 patients with knee
pain. Magnetic resonance imaging of the knees were carried out on a 1.5 T scanner with proton density weighted,
fat suppressed sequence in three
orthogonal planes. Ultrasonographic evaluations of the knees were performed in
both longitudinal and transverse planes. Taking the findings of magnetic
resonance imaging as a reference, the
diagnostic effectiveness of biplanar US in detecting medial condylar, lateral
condylar and intercondylar notch cartilage lesions were calculated.

Results: The sensitivity of biplanar ultrasonography in
detecting medial condylar, lateral condylar, and intercondylar notch cartilage
lesions were 93.55%, 61.11%, and 53.85%, respectively. The specificity of the
technique in detecting the lesions in these locations were 88.89%, 90.91%, and     100.00%, respectively.

 Conclusion: Ultrasonography is a
relatively inexpensive, easily accessible and a non-invasive imaging tool. We
found that biplanar ultrasonography is a reliable method in detecting medial
condylar cartilage lesions in knee osteoarthritis, and we recommend using it
for the purposes of screening and follow-up evaluation of medial type knee
osteoarthritis where MRI is not accessible.

Biplanar ultrasonografik incelemenin femoral artiküler kıkırdaktaki dejeneratif değişiklikleri saptamadaki tanı değeri

Abstract

Amaç: Manyetik rezonans görüntüleme referans alınarak,
transvers ve longitudinal yaklaşımların beraber kullanıldığı biplanar
ultrasonografik incelemenin, femoral artiküler kıkırdaktaki dejeneratif
değişiklikleri saptamadaki tanı değerinin saptanması amaçlandı.

Gereç
ve Yöntemler: Diz ağrısı
şikayeti olan 40 hastada ultrasonografi ve manyetik rezonans görüntüleme ile
femoral artiküler kıkırdak incelemesi yapıldı. Manyetik rezonans görüntüleme,
1.5 T görüntüleyicide her üç ortogonal düzlemde proton dansite ağırlıklı sekans
kullanılarak uygulandı. Diz ultrasonografi incelemesi, transvers ve
longitudinal planlarda gerçekleştirildi. Manyetik rezonans görüntüleme
bulguları referans alınarak biplanar diz ultrasonografi incelemesinin medial
kondil, lateral kondil, ve interkondiler çentik lokalizasyonlarındaki kıkırdak
lezyonlarını saptamadaki tanısal etkinliği hesaplandı.

Bulgular: Biplanar ultrasonografinin medial kondil, lateral
kondil, ve interkondiler çentik lokalizasyonlarındaki lezyonları saptamadaki
sensitivitesi aynı sıra ile %93,55, %61,11 ve %53,85, ve spesifisitesi aynı
sıra ile %88,89, %90,91 ve %      100,00
bulundu.

Sonuç:
Ultrasonografi
nispeten ucuz, kolay ulaşılabilir ve noninvaziv bir inceleme yöntemidir.  Biplanar ultrasonografi tekniğinin diz
osteoartritindeki medial kondiler kıkırdak lezyonlarını saptamada güvenilir bir
inceleme metodu olduğunu saptadık ve medial tip diz osteoartriti taraması ve MRG
erişiminin kısıtlı olduğu durumlarda takip değerlendirmesinde kullanımını
öneriyoruz.
