“…The only other modality that competes with Ultrasonography for this role is computed tomography (CT). 7 With these views in mind, we studied to evaluate and detect co-relation between Imaging and cytopathological features of space occupying lesions of liver in a given population. The prospective longitudinal type Study carried out at tertiary health centre of Patients.…”

Background: Liver is a common site for Space occupying lesions. It is difficult to distinguish these entities with imaging criteria alone. Development in liver surgery and liver pathology have led to many new types of primary hepatic space-occupying lesions (PHSOLS) being surgically resected and pathologically diagnosed, which has greatly increased the surgicopathological spectrum of PHSOLS.Methods: A 2-year tertiary care teaching hospital based longitudinal study with 77 participants was done. Selection criteria was defined and a prestructured proforma was made to assess and note the findings.Results: The mean age of occurrence of space occupying lesions of liver was 45.49±13.45 years with a range of 24 to 70 years. Space occupying lesions of liver was commonly observed in 4th Decade of life. 64.93% pathology of Space Occupying Lesions of Liver occur in males. 76.62% patients of space occupying lesions of liver present with pain in right upper quadrant.Conclusions: Majority of space occupying lesions were surgically managed with a short-term follow-up of 1 month in which no complications were noted.

Leeds LS9 7TFIt has been shown that ultrasound and static isotope imaging are relatively insensitive for the detection of lesions <2cm diameter (Bryan et al., 1977). CAT scanning, although apparently more sensitive than these 2 methods still appears to have a limitation in detecting small lesions in the liver (Scherer et al., 1978). However, since it has been established that intrahepatic primary or secondary tumours are associated with an increased hepatic arterial blood flow (Breedis & Young, 1953) and time-activity curves generated. The time of the peak of the kidney curve was used to indicate the division between arterial and portal inflow phases of the liver curve. The quality of the bolus injection and its distribution was assessed by examination of the rise time of the kidney curve and studies were rejected if this was greater than 8 sec. After 3-point smoothing of the liver curve the average slopes of the 2 consecutive 8-second sections on either side of the arterial/portal division were calculated. The first slope was taken to represent arterial inflow and the second slope was taken to represent the portal inflow. The hepatic perfusion index (HPI) was expressed as a fraction of the arterial inflow to the total hepatic inflow. Static scans were independently assessed (P.J.R.) as being indicative or non-indicative of the presence of hepatic metastases. The results of the static and dynamic studies were correlated with findings at laparotomy for the presence or absence of hepatic metastases, which where possible were measured. The sites of these metastases were also noted. Figure 1 shows the distribution of HPI values in the positive laparotomy group, in the group of patients with no liver metastases and in the control group. It can be seen that 24/25 patients who were in the laparotomy positive group (96%) had HPI values above the normal range, the upper limit of normal in this series being 0.42. One patient with massive hepatic replacement by tumour had an HPI value of 0.15 but interestingly had a positive static scan. In those patients known to have hepatic involvement, the sensitivity of static scanning was 64%. Nine patients in this group had normal scans, but all had abnormal HPI values. The data for the negative laparotomy group are also shown but no definitive statement can be made until the follow-up

“…Metastases to the liver are imaged by US with an accuracy equal to or exceeding that of CT or nuclear imaging [8]. The above cases demonstrate the value of CT in confirming the presence and defining the character (solid versus cystic) of L U Q masses.…”

Gastric neoplasm: Ultrasound and CT evaluation

Ultrasound may complement conventional barium evaluation of the upper gastrointestinal tract. Thirty cases of gastric neoplasm were evaluated with ultrasound; 8 of these patients also were evaluated with CT. The different sonographic appearances of gastric neoplasms will be presented based on these cases and a review of the literature. The specificity of these changes is discussed. In addition, the complementary role of CT scanning in the evaluation of gastric neoplasms is described.
