Abstract
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.

Abstract
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, 11 female; mean age 57.9+/-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.

Abstract
Magnetic resonance angiography and digital substraction angiography (DSA) findings in a case with a rare congenital thoracoabdominal aortic hypoplasia and common celiamesenteric trunk variation with occlusion of infrarenal abdominal aorta are described here. To our knowledge, this aortic anomaly has not been previously described in the English literature. DSA is the optimum imaging modality for determination of aortic hypoplasia, associated vascular malformations, collateral vessels, and direction of flow within vessels.

Abstract
PURPOSE Contrast enhancement patterns of parathyroid adenomas in the arterial and venous phases were evaluated with multidetector computed tomography and specificity of the method to characterize the lesions was investigated. MATERIALS AND METHODS Arterial and venous enhancement patterns of parathyroid adenomas were evaluated retrospectively with multidetector computed tomography in 12 patients. All adenomas were removed surgically and the diagnosis was confirmed histopathologically. An area from the mandibular angle to the aortic arch was scanned with 1.5 mm section thickness in the arterial phase (20 seconds delay time) and venous phase (70 seconds delay time) after bolus injection of 50 ml of iodinated contrast media. Arterial and venous contrast enhancement of parathyroid adenomas was evaluated in the axial and coronal reformat images. RESULTS Ten (83.3%) of 12 parathyroid adenomas showed a heterogeneous enhancement with a hypodense small central area in the arterial phase and a homogeneous enhancement in the venous phase. However, two small lesions, four and five mm in diameter respectively, showed homogeneous contrast enhancement in the arterial phase unlike the larger lesions which displayed a hypodense center in this phase. CONCLUSION Dynamic scanning with multidetector computed tomography after contrast administration may be helpful in characterizing parathyroid adenomas.

Abstract
PURPOSE To evaluate the effectiveness of percutaneous treatment under sonographic guidance in abdominal hydatid cysts. MATERIAL AND METHODS Fifty-two hydatid cysts in 33 patients were treated using a percutaneous approach under sonographic guidance. Forty-five cysts were located in the liver, 6 in the spleen, and 1 in the pancreas. Forty-nine cysts were type I, and 3 were type II. Thirty-one cysts in 15 patients were treated with puncture and aspiration of the contents, injection of hypertonic saline solution, and respiration (PAIR); 15 cysts in 14 patients were treated with puncture, aspiration of cyst contents, injection of hypertonic saline solution, drainage, and injection of sclerosing agent (PAIDS); and 6 cysts in 4 patients were treated with puncture, aspiration of cyst contents, injection of sclerosing agent, and re-aspiration (mPAIDS). Hypertonic saline or alcohol was used as a scolicidal agent. The follow-up period was between 17 and 53 months. RESULTS A decrease in the dimensions of the cysts, solidification of the contents, and irregularity in the walls of cysts, all of which were considered signs of cure, were found in all patients. Recurrence was observed in one case and anaphylaxis in one. CONCLUSION Percutaneous treatment of abdominal hydatid cysts is a safe, easily applicable, well-tolerated, and effective method.

Abstract
The purpose of this study was to evaluate the feasibility of using an open-configuration magnetic resonance (MR) imaging system with MR fluoroscopic guidance to perform percutaneous transthoracic fine-needle aspiration biopsy in patients with lung masses. Percutaneous transthoracic aspiration biopsies were performed with MR fluoroscopic guidance in 14 patients. The masses were 2-7 cm in diameter (mean, 4.1 cm). The needle was positioned by using a free-hand technique with MR fluoroscopic guidance. The needle tip reached the target lesion, and biopsy was performed. Analysis of the biopsy specimens facilitated a specific diagnosis in all patients. Pneumothorax was noted in two patients (14%) with chronic obstructive pulmonary disease. Study results showed that the described MR fluoroscopy-guided transthoracic biopsy technique can be used safely and successfully for lung masses. MR fluoroscopy can be used to reach the target lesion easily and accurately.

Abstract
The cerebral blood flow velocities (CBFV) of infants with perinatal asphyxia and hypoxic ischemic encephalopathy (HIE) in the first 12 hours of their lives have been the chief focus of our concern in this study. Cerebral ischemia which can develop in the earlier hours of HIE, and the detection and diagnosis of this condition with color Doppler ultrasonography (cD-USG) will be put into discussion. Twenty-three full-term newborn infants who had perinatal asphyxia and HIE together with a control group constituting twenty full-term newborn infants who produced no problems, were included in our study. All of the infants underwent cD-USG in the postpartum period of the first 12 hours (mean 8.4 hours). Measurements being based upon peak systolic velocity (PSV), end diastolic velocity (EDV) and Pouecelout's resistive index (RI) in anterior and middle cerebral arteries were conducted. The infants, having been discharged from the unit they were followed up for mean 9.8 months in the outpatient clinic. PSV and EDV counts in the postpartum first 12 hours of 23 infants who were detected to have HIE were found to be significantly lower compared to the control group, whereas RI counts were found to be significantly higher (p < 0.05). The counts obtained from the right and left cerebral arteries of the infants with HIE were found to be corraleted with each others. The neonates in the patient group were observed to have gone through this prognosis: Three of them died, three of them had cerebral palsy, one of them had infantile spasms, and three of them had developmental retardation. When we compared the CBFV of the 10 neonates who had poor prognosis, retrospectively with the other 13 neonates who had good prognosis, PSV and EDV were found to be significantly lower and RI significantly higher (p < 0.05). In the light of the data we have obtained, cD-USG can be considered to be a highly practical device in evaluating CBVF of the infants with HIE. A skillful detection of the decrease in cerebral blood flow which can develop in the postasphyxial first 12 hours and the prospective treatments being based upon this approach would contribute to the diagnosis, treatment and prognosis of such cases.

Abstract
The aim of this study was to show reduction of the diaphragmatic excursion with MR fluoroscopy in patients with chronic obstructive pulmonary disease (COPD) and to compare the results with pulmonary function test (PFT). The study included 13 men and 10 women (average age 56.2) with COPD, and 9 men and 6 women (average age 55.8) as a control group. MR fluoroscopy images with Spoiled Gradient-echo pulse sequence was obtained during deep inspiration and expiration. After examination, over cine-loop display, the highest and lowest positions of the diaphragm were identified and the distance of excursion was measured. Differences in the diaphragmatic excursion between patient and healthy subjects were compared. We have also compared MR fluoroscopy results with PFT. In each person of both groups, excursion of the diaphragm was demonstrated clearly in cine-loop display. Differences of excursion between deepest and highest point of diaphragm were on average 26 and 20 mm, respectively, in the right and left side in patients and 69 and 56 mm in healthy group. Significant correlation was found between expiratory volume in 1 s and MR fluoroscopy results. MR fluoroscopy study showed that there were significant statistical differences in diaphragmatic excursion between patients with COPD and healthy subjects. Expiratory volume in 1 s is closely associated with the diaphragmatic excursion. MR fluoroscopy would seem to be a useful method for showing diaphragmatic excursion.

Abstract
Duplex-Doppler study typically exhibits triphasic brachial artery blood flow velocity pattern in subjects classified as normal without clinically evident atherosclerotic complications, heart disease, hypertension, or diabetes mellitus. In this study, the authors described the late systolic wave on the brachial artery blood flow velocity pattern in patients with coronary artery disease and investigated the relation between late systolic wave and vascular stiffness. Blood flow profile and velocity of the brachial artery were determined noninvasively by ultrasound pulsed-Doppler technique under the guidance of a B-mode ultrasound image in 96 patients with coronary artery disease (CAD). The control group consisted of 23 healthy subjects with no or maximally 2 risk factors (only among age, cigarette smoking, obesity, and gender) for vascular disease. None of the patients and controls had clinical evidence of arterial disorders at upper extremities. In 32 patients (33%) with CAD, a late systolic wave was observed in the brachial artery Doppler study. On the other hand, no late systolic wave was observed in the healthy subjects. In addition, multivessel disease, hypertension, advanced age, diabetes, and smoking were significantly more frequent in patients with the late systolic wave. In conclusion, peripheral arterial abnormalities induced by vascular stiffness may produce alterations in regional wave reflections, and the normal triphasic pattern of the brachial artery blood flow may change by the appearance of the late systolic wave.

Abstract
The aim of this work was to show contribution of power Doppler imaging in the diagnosis of the carotid body tumors. Six patients with a nontender mass beneath the mandibular angle were evaluated with gray scale and power Doppler sonography. Well-defined, solid, weakly hyperechoic masses were noted on gray scale sonography in the carotid bifurcation. Power Doppler sonography showed abundant flow, characterized as an intense blush, throughout the entire tumor in all patients. We believe that invasive and expensive diagnostic modalities are not necessary to evaluate carotid body tumors. Gray scale sonography and power Doppler imaging are sufficient for primary diagnosis of carotid body tumors.

Abstract
In addition to color and pulsed Doppler sonography findings, we aimed to describe power Doppler sonography findings in Graves' disease in this study. Twenty-three patients with Graves' disease were imaged with gray-scale, color and power Doppler sonography. Twenty normal volunteers were examined by the same equipment and the same technique as a control group. A subjective grading system was used to categorize the vascularization in pulsed Doppler sonography images from normal to markedly increased vascularization. Power Doppler sonography exhibited diffuse hypervascularity in the thyroid gland in all patients. The flow was covering about all the parenchyma. Four patients showed mild, 12 patients moderate and seven patients marked vascularity. The intensity of power Doppler flow pattern was not correlated with the severity of the disease. This study demonstrated that power Doppler sonography is a convenient, time saving, inexpensive and noninvasive method as compared with isotope scan and some other laboratory tests for confirmation of Graves' disease.

Abstract
OBJECTIVE The aim of this study was to describe the duplex and color Doppler sonographic findings in active sacroiliitis. SUBJECTS AND METHODS Forty-one joints in 21 patients with active sacroiliitis, 20 sacroiliac joints in 10 patients with osteoarthritis, and 30 sacroiliac joints of 15 asymptomatic volunteers were investigated on duplex and color Doppler sonography. We investigated whether a vessel was present around the posterior portions of sacroiliac joints with color Doppler sonography. When an artery was detected, the resistive index (RI) was measured using duplex Doppler sonography in all groups and also after treatment in the patients with active sacroiliitis. RESULTS Vascularization around the posterior portions of sacroiliac joints was seen in 41 joints of the 21 patients with active sacroiliitis, nine joints of six patients with osteoarthritis, and 13 joints of eight volunteers. The mean RI values were 0.62 +/- 0.13, 0.91 +/- 0.09, and 0.97 +/- 0.03, respectively. In the patients with active sacroiliitis, the mean RI value was 0.91 +/- 0.07 after therapy. The RI values for the patients with active sacroiliitis were significantly different from those of the patients with osteoarthritis (p < .001) and of the volunteers (p < .001). In addition, the RI values were significantly different before and after treatment in the patients with active sacroiliitis (p < .001). CONCLUSION Vascularization around the posterior portions of sacroiliac joints increased and RI values decreased in patients with active sacroiliitis. Color and duplex Doppler sonography were able to reveal these changes and can be used in the diagnosis of active sacroiliitis and follow-up after treatment. Thus, RI values may be a quantitative indicator for clinical symptoms in patients with active sacroiliitis.

Abstract
This study was performed to determine whether power Doppler sonography is superior to color Doppler sonography in the depiction of the normal fetal intrarenal vasculature during pregnancy. Twenty-five fetal kidneys in 22 healthy fetuses between 22 and 40 weeks of gestation (mean 32.6 weeks) were studied with color and power Doppler sonography with a 3.75 MHz transducer. The efficacy of power and color Doppler sonography were compared in assessing fetal renal vasculature. Power Doppler sonography demonstrated diffuse "blush" in almost the entire cortex in 21 of 25 fetal kidneys, whereas it was demonstrated in half of the cortex in the other four kidneys. Color Doppler sonography failed to demonstrate a cortical blush in fetal kidneys. Power Doppler sonography has been shown to be superior to color Doppler sonography in the depiction of normal fetal intrarenal vasculature during pregnancy by demonstrating vascular blood flow better than color Doppler sonography.

Abstract
OBJECTIVE To evaluate the efficacy of power doppler ultrasonography in depicting increased vasculature and hyperemia around the superficial soft tissue abscess. MATERIALS AND METHODS 21 patients with soft tissue abscess were evaluated with gray scale imaging, color doppler sonography, power doppler sonography and computed tomography. In each case attempts were made using power doppler sonography to demonstrate any areas of increased vascularity around the lesion. The results were compared with computed tomographic findings. RESULTS Peripheral hyperemia and increased vasculature were demonstrated with power doppler sonography in 19 of 21 patients with soft tissue abscess. The hyperemic area demonstrated around the wall of the abscess by power doppler sonography was similar to the enhanced area shown by computed tomography performed after contrast administration. CONCLUSION Power doppler sonography shows increased vasculature and hyperemia in the wall of abscesses. Therefore, power doppler sonography can be used to assist with the diagnosis of superficial soft tissue abscess.

PATIENTS AND METHODS Thirty-six patients (mean age 66.4 years, SD 7.7, range 59-82) with possible prostate cancer, suspected from an abnormal digital rectal examination or elevated prostate specific antigen level, underwent transrectal ultrasonography, transrectal PDU and biopsy. The vascularity on PDU was graded on a scale of 0-2, where grade 1-2 was considered positive and grade 0 negative. RESULTS The vascularity was grade 2 in 11 patients, grade 1 in 11 and grade 0 in 14; 20 of the 36 (56%) patients had prostate cancer. Of the 22 patients positive on PDU, 18 had malignant disease and four benign; two of 20 patients with histopathologically confirmed malignancy had a normal PDU. The sensitivity of PDU was 90%, the specificity 75% and the positive predictive value 82%. CONCLUSION Focal hypervascularity on PDU was associated with an increased likelihood of prostate cancer. Although ultrasonography alone cannot detect all cancers, even using PDU, the technique appears to increase the sensitivity and to help identify appropriate sites for biopsy.

Abstract
In this prospective study, 43 chronic tonsillitis patients underwent intraoral ultrasonography preoperatively and the width and thickness of tonsils and tonsillocarotid distances were measured. Positive correlation was obtained in postoperative measurements compared with ultrasonographic measurements of tonsils. The mean tonsillocarotid distances were 8.6 mm in the left and 8.25 mm in the right tonsillar fossa. This study showed that preoperative intraoral ultrasonography was to be help of tonsillectomy operations particularly in surgical anatomical orientation.

Abstract
Echinococcosis, an endemic disease on the Asian continent, is caused by ecinococcus granulosus and rarely ecinococcus alveolaris. Although it occurs frequently in the liver and the lung, it can be localized in all tissues and organs. The purpose of this study is to report a rare localization and the complication of hydatid cyst in the pelvis : it pushed forward and upward the urine bladder and there was bilateral hydroureteronephrosis causing uraemia because of outflow obstruction. To our knowledge, a similar case has not been published before in English literature.

Abstract
Juvenile nasopharingeal angiofibroma (JNA) is a rare, histologically benign but clinically malign hypervascular tumor localized in the nasopharynx which occurs exclusively in adolescent boys. There is no definite attitude towards etiology of angiofibroma. In diagnostics, besides epypharyngoscopy, computed tomography and magnetic resonance imaging are the primary diagnostic tests. Angiography is used for preoperative embolization. In this case report, we aim to demonstrate the vascularity of JNA with power Doppler sonography (PDS) and advanced vasculature was observed into tumoral lesion with PDS.

Abstract
OBJECTIVE To assess the ability of power Doppler ultrasonography (PDU) to detect acute pyelonephritis and to compare the findings from PDU with those from enhanced computed tomography (CT). PATIENTS AND METHODS Eleven patients (mean age 18.5 years, range 5-37) admitted to hospital with a clinical diagnosis of pyelonephritis were assessed with PDU and enhanced CT. the latter providing the reference method. RESULTS The imaging studies showed normal findings in three patients; a single focus of pyelonephritis was detected by CT in six, whereas a matching defect was detected on PDU in five, with PDU failing to detect an infective focus in one. Multifocal diffuse pyelonephritis was diagnosed correctly by enhanced CT and PDU in two patients. CONCLUSION Power Doppler ultrasonography had an overall sensitivity of 88% and complete specificity in the evaluation of patients with acute pyelonephritis.

Abstract
We describe a case of pancreatic hydatid cyst in which the definitive diagnosis was made at fine needle aspiration cytology. The most common site of hydatid cyst is the liver (65%), followed by the lungs (25%). The hydatid cyst of the pancreas is rare since it accounts for less than 1% of the various sites of hydatid disease. The diagnosis may be difficult when the presentation is that of an unexplained epigastric mass or cyst, despite suggestive radiological and ultrasonographic features. Modern serology tests are positive in up to 80% of the abdominal hydatid cysts. It is mandatory to obtain a fine needle aspiration biopsy for definite diagnosis and for appropriate treatment planning. Surgical removal of the hydatid cyst still remains the most effective treatment.
