Bronkojenik Kist: Olgu Bildirimi
(2000) Etlik, Ömer; Uzun, Kürşat; Gencer, Mehmet; Temizöz, Osman; Sakarya, Mehmet Emin
Bronkojenik kişiler trakeobronşial ağacın anormal tomurcuklanması sonucu oluşur. Genellikle orta mediastende ve karinaya komşu olarak yerleşirler. Bronkojenik kist öksürük ve dispneye neden olabilir. Göğüs radyografisinde orta medtastende yuvarlak veya oval kitle şeklinde görülür. Bilgisayarlı tomografide kist veya solid kitle yoğunluğunda kitlenin görülmesi ile bronkojenik kist tanısı düşünülür. Bu makalede, öksürük ve dispneye neden olan bronkojenik kist olgusu radyolojik bulguları ile birlikte sunulmuştur.
Detection and Quantification of the Parenchymal Abnormalities in Emphysema Using Pulmo-Ct
(Pergamon-elsevier Science Ltd, 2007) Temizoz, Osman; Etlik, Omer; Sakarya, Mehmet Emin; Uzun, Kursat; Arslan, Halil; Harman, Mustafa; Demir, Mustafa Kemal
We aimed to determine the degree and extent of parenchymal abnormalities on pulmo-CT in patients with emphysema. The study group consisted of 29 patients (18 male, I I female; mean age 57.9. L 13). The diagnosis was based on clinical symptoms, pulmonary function tests (PFT) values, and chest CT findings. All of the patients CT scans were obtained during suspended deep inspiration from the apices to the costophrenic angles. The mean lung attenuation (MLD) and parenchymal abnormalities related to emphysema were quantitatively calculated with tables, histograms and graphics at the whole lung. The lung density measurements revealed a mean density of -898.48 +/- 51.37 HU in patients with emphysema and -825.1 +/- 25.5 HU in control group. In addition, mean percentage of subthreshold attenuation values was found as 12.03 +/- 15.75 and 1.07 +/- 0.83 in patients with emphysema and control group, respectively. Compared with control group, the patients with emphysema had a significantly lower inspiratory MLD (p < 0.05). Additionally, statistically significant correlations were seen between the MLD and percentage of subthreshold values (r = 0.44, p < 0.05). In contrast, there was poor correlation between PFT measurements and the subthreshold values. In conclusion, pulmo-CT is a quick, simple method for quantitative confirmation of the presence of parenchymal abnormalities of lung as mosaic attenuation and should be used in combination with other radiological methods and PFT as it gives additional information to routine examinations in patients with emphysema.

Paratiroid Adenomu Tanısında Çok Dedektörlü Bt: Kontrast Tutulum Paterninin Tanıya Katkısı
(2004) Sakarya, Mehmet Emin; Harman, Mustafa; Etlik, Ömer; Algün, Ekrem; Ayakta, Hayati
AMAÇ Paratiroid adenomlarının arteryel ve venöz fazda kontrast tutulum paterni çok dedektörlü bilgisayarlı tomografi ile değerlendirildi ve yöntemin lezyonu karakterize etmedeki duyarlılığı araştırıldı. GEREÇ VE YÖNTEM Paratiroid adenomlu oniki hastaya ait kontrastlı çok dedektörlü bilgisayarlı tomogafi bulguları retrospektif olarak değerlendirildi. Hastaların tümünde adenomlar cerrahi yolla çıkarılarak tanı histopatolojik olarak doğrulandı. Bilgisayarlı tomografi incelemede mandibula angulusundan, üst mediastende arkus aorta düzeyine kadar mesafe taranarak 1.5 mm’lik kesitler elde edildi. Aynı işlem hastaya 50 ml kontrast madde bolus tarzında verildikten sonra 20. (arteryel faz) ve 70. saniyede (venöz faz) tekrar edildi. Bu üç inceleme sonunda elde edilen görüntülerden paratiroid adenomuna ait kitle lezyonun arteryel ve venöz fazdaki boyanma paternleri aksiyel ve rekonstrükte koronal imajlarda değerlendirildi.BULGULAR Oniki paratiroid adenomundan 10’unda (%83.3) arteryel fazda santral veya parasantral küçük nodüler bir alan dışında tiroid bezine yakın yoğunlukta minimal heterojen boyanma, venöz fazda ise santraldaki alan da dahil tüm lezyonun homojen boyandığı görüldü. Boyutları 4 ve 5 mm olan iki lezyonun ise hemen arteryel fazda tiroid bezi ile eş zamanlı olarak santral bölge dahil tamamen homojen olarak boyandığı görüldü.SONUÇ Paratiroid adenomlarının tanısında çok dedektörlü bilgisayarlı tomogafi cihazı ile yapılacak kontrastlı dinamik inceleme lezyonu karakterize etmede tanıya yardımcı bir modalite olarak kullanılabilir.
Pulsatility Index of Popliteal Artery in Patients With Isolated Calf Vein Thrombosis: a Novel Technique for Detecting Thrombosis
(int Scientific information inc, 2017) Batur, Abdussamet; Polat, Vural; Ozgokce, Mesut; Alpaslan, Muhammed; Yavuz, Alpaslan; Arslan, Harun; Sakarya, Mehmet Emin
Background: To investigate the usefulness of popliteal artery spectral doppler findings as a complimentary approach to isolated calf vein thrombosis (DVT). Material/Methods: We included consecutive patients presenting with symptomatic and sonographically proven acute isolated calf DVT. Patients with thrombosis of any other vein were excluded. We classified calf vein into into four main types. We investigated how many of these four vessels had DVT and compared them with respect to the pulsatility index (PI) value of the popliteal artery. Results: We evaluated spectral doppler characteristics of the popliteal artery on the same side as the isolated calf vein thrombosis as well as on the opposite side. The relationship between PI values of the popliteal artery and the number of thrombosed calf veins was investigated. In patients with 1 and/ or 2 thrombosed veins, the mean PI was 6.03+/-0.54 on the side of cDVT and 5.68+/-0.39 on the opposite side (p=0.008), respectively. Inpatients with 3 and/ or 4 thrombosed veins, the mean PI was 8.05+/-0.61 on the side of cDVT and 6.34+/-0.47 on the opposite side (p=0.001), respectively. Conclusions: Venous doppler sonography for the evaluation of calf DVT may be limited by patient characteristics such as obesity, edema, and tenderness., Arterial PI can be used as a complimentary technique for the detection of venous thrombosis in such of cases.
